CCS Coair, Skynet UAL, EresPassrider Login and FAQ

CCS CoAir, Skynet UAL and eResPassrider Login and FAQ.

All your questions answered about CCS CoAir, Skynet UAL, Flyingtogether, and eResPassrider

CCS is a legacy name that still shows up across United’s internal tools and documentation. It originally referred to the Crew Communications System used by Continental Airlines (“CoAir”), and after the merger, the name continued to be used in various workflows, links, and references.

Today, United employees will most commonly run into “CCS CoAir” when trying to:

Access crew scheduling functions (viewing schedules, reserve status, assignments, swaps/trades depending on role and workgroup)
Launch scheduling-related tools from Flying Together
Troubleshoot sign-on issues (SSO, MFA, browser/cookies, network access)

Please refer to the extensive FAQ at the end covering the most common questions and problems people report online.

Quick links (official sign-in paths)

Most United work tools are accessed through Flying Together and/or UAL’s Single Sign-On.

Note: some links may only work on the United network, VPN, managed devices, or for certain employee groups. If a link opens but shows an access/eligibility error, that can be a permissions or network-context issue (not necessarily “down”).

What CCS CoAir is (and what it is not)

What it is

CCS CoAir is best thought of as a crew scheduling access point and a legacy naming layer that routes you into scheduling functions. “CoAir” is the historical Continental label; many internal systems keep these legacy identifiers for compatibility.

What it is not

CCS CoAir is not a public consumer website, and it is not the same thing as:

eRes (employee travel / pass travel tools)
Skynet UAL (often used as a shorthand for an internal inflight scheduling/satellite-base workflow; the exact tool name people mean can vary)
United.com (customer-facing booking and account tools)

How access usually works at United (SSO, network, and roles)

Most United internal apps follow a similar pattern:

You start at Flying Together (or a deep link from email/training docs).
You authenticate via UAL sign-on / SSO (username + password + MFA if required).
Your workgroup role (pilot, inflight, airport ops, corporate, etc.) controls what you can see.
Your network context (United network, VPN, managed device, or public internet) can affect access.

If you ever see messages like “not eligible,” “not authorized,” or “merchant not eligible,” treat them as an access context / permissions problem first (not necessarily a “broken site”).

How to log in to CCS CoAir (common pathways)

Option A: Start from Flying Together (recommended)

This is the most stable method because Flying Together links usually handle routing and current sign-on rules:

Go to Flying Together.
Sign in via SSO if prompted.
Open the scheduling tool from the official internal page (not from random saved bookmarks).

Option B: Use the direct CCS entry link (if permitted)

Some employees can reach CCS via:

https://ccs.ual.com/CCS/default.aspx

If it redirects, prompts repeatedly, or fails to load, jump to the troubleshooting section below. Many access issues come down to cookies, SSO sessions, or being off-network.

Skynet UAL Login:

SkyNet at United Airlines (UAL) is
the United Airlines company’s legacy internal employee portal and intranet system, used for accessing work schedules, travel benefits (pass travel), payroll, and news, often accessed via the “FlyingTogether” platform. It is a central hub for employee self-service.

United Airlines employee portal (formerly often referred to as Skynet/Empres) is accessed via Flying Together at https://flyingtogether.ual.com or https://ft.ual.com. Employees log in using their File Number (uID) and password to access company resources, payroll, and benefits.

The UAL Skynet Login Official Portal URL is : https://flyingtogether.ual.com
Alternative URL: https://ft.ual.com

Username Format: Often uses u + file number (e.g., u05xxxx), ensuring a zero is used instead of the letter “O” if applicable.

eRes Ual Login (eResPassrider)

eRes is the employee travel environment (pass travel, listings, traveler profile management depending on your permissions). It’s commonly accessed via:

https://eres.ual.com/

Important: eRes is not the same as crew scheduling (CSS CoAir). However, many employees confuse them because both are accessed via Flying Together and both involve sign-on, eligibility, and role-based access.

United Airlines employees and eligible pass riders access EmployeeRES (eRES) for standby travel via https://eres.ual.com/, requiring a uID/username and password.

Employees manage listings there, while enrolled friends/family may get specific logins or use the United app if linked by the employee.

Main Login URL: https://eres.ual.com/

Pass Rider Specific Link: https://erespassrider.ual.com/employeeres/passriderlogin.aspx

Buddy Passes: Cannot have their own login; employees must book for them.

Enrolled Friends/Family: Can sometimes get separate logins or link MileagePlus to the United app if set up by the employee.

Pass rider and traveler access has been shifting toward linking a MileagePlus account and using the United app for certain actions, rather than relying on separate “buddy/passrider” web logins. If a pass rider cannot log in the way they used to, that can be policy-driven rather than a technical failure.

Best practices: avoid the most common access problems

Use Flying Together first for the “official route” and current links.
Avoid old bookmarks saved years ago. Internal paths change.
Try a private/incognito window only as a test. If it works there, you likely have a cookie/session conflict.
Allow cookies for United domains when using SSO-based apps (SSO often depends on cookies).
Try a different browser if you’re stuck in a sign-in loop (Chrome/Edge differences can matter).
Disable extensions that intercept traffic (privacy/VPN/proxy/“security” add-ons). These can cause redirects, blank pages, or odd eligibility errors.
Confirm network context: some internal tools require United network/VPN/managed device.

Troubleshooting CCS CoAir, Skytal, and eRes

1) Sign-in loop (keeps returning to login)

Most often caused by a cookie/session problem:

Clear cookies for United/UAL domains (or clear all cookies if you can).
Close all browser tabs, reopen, and try again.
Try a different browser profile (separate work profile helps).
Temporarily disable extensions, especially VPN/proxy/privacy tools.

2) “Not authorized” / “Not eligible” messages

Common causes include:

You are not in the correct employee group for that tool.
You are off-network and the tool requires VPN/managed device.
Your SSO session is valid but your app authorization token is not (log out fully and back in).
The link is old and points to a retired page.

Fix: start from Flying Together and open the tool from the current hub page, then re-check access from the correct network context.

3) Blank page / endless loading / “please wait”

Try:

Hard refresh (Ctrl+F5 on Windows).
Disable ad blockers and privacy blockers for United domains.
Try Edge if Chrome fails (or vice versa).
Confirm JavaScript is enabled.
Test from a different network (home vs hotspot) only if policy allows.

4) MFA issues

If MFA prompts are not appearing or are failing:

Confirm your device time is correct (time drift can break authenticator flows).
Re-try from Flying Together so SSO handles the correct authentication path.
If you changed phones, you may need re-enrollment through official IT channels.

5) “This site can’t be reached” / DNS / certificate errors

This can happen if:

You’re on a network that blocks corporate subdomains.
You’re behind a VPN/proxy that interferes with certificates.
The tool is restricted to United network access.

Fix: disable non-United VPN/proxy, try from the official network route, and use Flying Together as the launch point.

Security note (very important)

Internal tools attract phishing attempts and “lookalike” pages. Protect yourself:

Prefer starting from Flying Together rather than clicking unknown links.
Check the domain carefully (United internal domains are typically under ual.com).
Do not enter credentials into random “help” sites or popups.
If something behaves like malware (popups, redirects, “merchant not eligible” odd pages), check your browser extensions and run security scans.

FAQ – CCS CoAir, Skytal UAL, and eRes.

What does “CCS CoAir” stand for?

It’s shorthand for “Crew Communication System – Continental Airlines.” “CoAir” is a legacy Continental identifier that persists in internal naming even after the merger.

Is CCS CoAir the same thing as Flying Together?

No. Flying Together is the employee portal and launch point for many tools. CCS CoAir is a scheduling system reference or entry point that you typically reach through Flying Together or a direct internal link.

Is CCS CoAir only for pilots?

No. Crew scheduling tools can be relevant to multiple workgroups. What you see depends on your role, permissions, and the internal apps your department uses.

Why do people still say “CoAir” at United?

It’s mostly legacy terminology. Internal systems, documentation, and even URLs can keep older labels for compatibility and continuity.

What is the safest way to access CCS CoAir?

Start from Flying Together and navigate from the official scheduling hub for your workgroup. That route is most likely to be current and properly authenticated.

What is the direct CCS link people share?

A commonly shared legacy entry is:

https://ccs.ual.com/CCS/default.aspx

Access can be restricted by network context and role.

Where do I log in for eRes?

eRes is typically accessed via Flying Together or the eRes entry at:

https://eres.ual.com/

Why does eRes sometimes say a pass rider can’t create a login?

Online discussions suggest some pass rider access has been changing over time, with more emphasis on linking a MileagePlus account and using the United app for specific pass-travel tasks rather than separate web logins.

I’m stuck in a login loop. What’s the first thing to try?

Clear cookies for United/UAL domains, close all tabs, reopen the browser, and launch the tool from Flying Together instead of a bookmark. Then disable extensions that might interfere (VPN/proxy/privacy).

Why does it work on my work computer but not at home?

Some internal tools require United network context, VPN, or a managed device. Home networks plus privacy extensions can also break SSO flows.

Can browser extensions break CCS CoAir or eRes?

Yes. Extensions that inject scripts, block cookies, rewrite links, force proxies, or filter traffic can cause redirects, blank pages, or unexpected eligibility errors.

What should I do if I see a weird “eligibility” or “merchant” error?

Treat it as suspicious until proven otherwise. Disable extensions, confirm the domain is correct, relaunch from Flying Together, and run security checks if redirects or popups continue.

Which browser works best?

It varies, but if one browser loops or loads blank pages, try another (Chrome vs Edge). Many SSO issues are browser-profile or cookie-policy related.

Do pop-up blockers matter?

They can. Some enterprise tools open new windows for authentication or embedded modules. If something won’t open, try allowing popups for United domains.

What if the site loads but I’m told I’m not authorized?

That usually means your role doesn’t have access to that module, or you’re not in the correct network context. Launch from the correct workgroup page on Flying Together and try again.

Why did my old bookmark stop working?

Internal paths change. Bookmarks often point to retired pages or require a new authentication method. Replace the bookmark with the current Flying Together hub page.

What if Flying Together itself won’t load?

Try a different browser, disable extensions, check your network, and confirm you are using the official domain:

What is the UAL sign-on page?

A commonly referenced SSO entry is:

https://signon.ual.com/

How do I fully “log out” to reset a broken session?

Close all browser tabs, clear cookies for United/UAL domains, then open a fresh browser window and start again from Flying Together. Partial logouts often leave stale tokens in place.

Why do I keep getting redirected between sites?

SSO tools pass tokens between domains. If cookies are blocked or an extension rewrites requests, the token exchange fails and you can get stuck bouncing between pages.

Does using a personal VPN cause problems?

It can. Some VPN endpoints trigger security checks, block corporate subdomains, or interfere with certificates. If you are allowed to, disable personal VPNs and retry.

Can I access these tools on a phone?

Some functions work on mobile and some do not. If a tool is designed for desktop or requires popups/embedded modules, mobile browsers can struggle. If you’re troubleshooting, test from a desktop browser.

What if my password works on one tool but not another?

That can happen if you’re actually signing into different identity systems, or if one tool is failing to complete SSO properly. Start from Flying Together to ensure you’re using the correct authentication path.

How do I handle “account locked” messages?

Use the official password reset/unlock flow through United IT channels and Flying Together. Avoid third-party “reset” sites or links from search results.

What’s the difference between CCS and eRes?

CCS is scheduling-focused (crew work), while eRes is travel-focused (pass travel and employee travel functions). They are different tools even if the sign-on experience looks similar.

Is “eRes” the same as employeeRES?

Employees often use these names interchangeably. In practice, many travel functions live behind the eRes environment accessed from Flying Together.

Why does eRes sometimes show policy reminders for pass riders?

Pass travel policies and tooling can change, and eRes is where reminders and workflow shifts often appear. If something changed “overnight,” it can be a policy/tool migration rather than an outage.

Where should I look for the most current pass travel policy?

For the most current policies, United employee resources often point back to Flying Together’s Travel section. A retiree association page also emphasizes checking Flying Together for the latest travel policy details.

What number do people cite for IT help with Flying Together password resets?

A retiree resource page lists a United Digital Technology Service Desk number for Flying Together password resets. Always verify the current number inside Flying Together because contact routes can change.

My page loads but buttons don’t work. Why?

Usually JavaScript is being blocked by a privacy tool, a strict browser setting, or an extension. Temporarily disable blockers for United domains and try again.

Why do I see different options than my coworker?

Permissions differ by role, base, workgroup, seniority rules, and assigned access. Two employees can be “in the same company” but not have the same entitlements in a scheduling system.

Can I fix an access problem by switching networks?

Sometimes. If you’re on a network that blocks corporate subdomains, switching can help. But if a tool requires United network/VPN, switching away can also make it worse. Use the official access method your department recommends.

What’s the fastest “basic checklist” before I call support?

Confirm you are using an official United domain (ual.com)
Launch from Flying Together (not a bookmark)
Disable extensions (especially VPN/proxy/privacy)
Clear cookies for United domains
Try a different browser
Confirm network context (United network/VPN if required)

I need to manage my schedule but I can’t find the right page. What should I search for?

Inside Flying Together, try searches like:

crew scheduling
schedule
reserve
inflight scheduling
satellite bases
CCS

Why do some internal links only work when clicked from Flying Together?

Because Flying Together may set session context, pass tokens, and route you through the approved authentication chain. Direct links can fail if they skip those steps.

Can a corrupted browser profile cause ongoing issues?

Yes. If the same problem persists after cookie clears, try a fresh browser profile or a different device. Profiles can keep conflicting settings and stale tokens.

Is it normal to see “Continental” references in 2026?

Yes. Many large enterprises keep legacy naming and backend identifiers long after mergers. It’s common in internal toolchains.

Does United publish public documentation for CCS CoAir?

Not typically. Most documentation is internal. Public internet discussions are usually high-level and focused on access problems rather than detailed system instructions.

What should I do if I think a “CCS CoAir help site” is asking for my password?

Do not enter credentials. Use official United domains and sign-on pages only. Report suspicious sites using your organization’s security process.

Where can I find official United mobile app info?

United’s official page for the app is here:

https://www.united.com/en/us/fly/travel-experience/united-app.html

What’s a good habit to prevent future access issues?

Bookmark only the top-level Flying Together hubs (not deep legacy pages), keep extensions limited on your “work” browser profile, and refresh your bookmarks if an internal page changes.

How do I report a persistent outage vs a local browser problem?

If multiple coworkers in your location/workgroup see the same issue at the same time, it may be an outage. If it’s only you, it’s more likely cookies/extensions/network context. When reporting, include the exact error text and the URL domain (not your credentials).

Can I share screenshots of CSS CoAir errors publicly to get help?

Be careful. Internal pages may contain sensitive info. If you need help, use official support channels or internal forums, and redact personal/secure details.

What if I need help with pass travel policy questions?

Use Flying Together’s Travel section as the primary source. A retiree association page also emphasizes that Flying Together is the correct place to find current policy guidance.

Is there a single “one-size-fits-all” guide for every workgroup?

Not really. This article focuses on the shared access patterns (Flying Together, SSO, cookies, network context) and the most common problems. For the exact buttons and workflows you should follow, use your workgroup’s official internal training pages.

What’s the most common reason people think CSS CoAir is “down” when it isn’t?

Old bookmarks and blocked cookies. Many “down” reports are actually authentication loops caused by stale sessions or blocked third-party cookies required for SSO token exchanges.

What’s the most common reason people think eRes is “broken” when it isn’t?

Policy/workflow changes (especially for pass riders) plus confusion between different account types (employee vs enrolled friend vs buddy pass) and where each is allowed to log in.

What if none of this works?

At that point, it’s reasonable to contact United’s official internal support path and provide the exact error text, the domain you’re trying to access, and whether you are on-network or off-network. Support can confirm whether it’s an entitlement issue, a known outage, or an account/MFA problem.

What is “Skynet” at United (UAL), and how is it related to non-rev / pass travel?

“Skynet” is a nickname many United employees use for the internal pass travel / listing tools inside United’s employee ecosystem (often accessed through Flying Together / employee travel links). It’s typically where eligible travelers get flight loads, list for standby, and manage pass travel options depending on their status and privileges. If you can’t see certain features, it’s often because your account role (employee vs dependent vs enrolled friend) controls what modules you’re allowed to access.

What is eRES / EmployeeRes, and is it the same thing as Skynet?

eRES (sometimes referred to as EmployeeRes) is the employee travel/reservations system used for standby listings and pass travel workflows. People sometimes say “Skynet” when they mean “the place in the intranet where I list/check loads,” but the terms get used loosely in forums. Practically, you’ll hear both terms around pass travel, listing, and priority codes, even if they aren’t identical systems.

What is ERES Passrider (erespassrider), and who uses it?

ERES Passrider is the pass rider portal experience used by non-employees (like dependents or enrolled friends) to list for standby and review loads/eligibility depending on how the employee sponsors them. Access is usually tied to the sponsoring employee’s setup and whatever identity linkage United requires (often including a MileagePlus number). If something changes in your sponsor profile, it can affect what you can see or do in Passrider.

I heard pass riders can’t list through eRES anymore and must use the United app. Is that true?

Recent discussions from pass riders and employees indicate that some NRSA/pass rider listing workflows moved away from the eRES site and into the United app for certain users. If you suddenly can’t list the old way, it may be because your pass rider category is now expected to list in-app (and the eRES path may be restricted). If the app is glitching, people often recommend re-checking that your MileagePlus linkage is correct and trying a fresh login/session.

Why does erespassrider say “Your account is no longer valid”?

That message is commonly reported when your access token/credentials are out of date, your sponsor’s eligibility changed, or your profile link (often to MileagePlus) isn’t recognized correctly anymore. It can also happen after password/security changes or if your sponsor needs to re-confirm your details in Flying Together. A practical first step is to have the sponsoring employee verify your pass rider profile is still active and correctly linked.

The “Sign In” button on ERES Passrider doesn’t do anything. How do people fix that?

This is frequently a browser/session issue (blocked scripts, stale cookies, or an incompatible browser mode). People typically fix it by switching browsers, disabling extensions/ad-blockers, clearing site cookies for the United/Passrider domain, and trying again in a normal (non-incognito) window. If you’re on mobile, trying desktop mode (or the reverse) can also change whether the button responds.

What does “SA Listed” mean vs “Standby List” when I’m checking loads?

In pass travel discussions, “SA Listed” is often used as a count of space-available travelers listed for that flight (sometimes broken out by cabin/service buckets). “Standby List” can be confusing because some views mix different standby types (employee non-rev, revenue standby, and other categories) depending on where you’re viewing it. If the numbers don’t match, it can be because one view is counting more than just pass riders.

Why don’t I see my name on the standby list after I list?

Sometimes the list display is delayed, filtered, or shows only certain categories unless you’re fully checked-in/within a particular time window. United’s public standby guidance also notes that if you don’t see your name, airport agents may be the only ones who can resolve it at the airport for that situation. If you’re a pass rider, confirm you completed every step (listing + any required check-in step) and that you’re looking at the right flight/date.

How do boarding priorities work for United non-rev travel, and where do I see my code?

United non-rev priority is based on your traveler type (employee, eligible dependent, enrolled friend, etc.), pass type, and sometimes other factors like check-in time or specific agreements. People often see a code/position in the employee travel tools (the place they call “Skynet”) but find it hard to interpret without a reference chart. The most reliable explanation is usually the official pass travel materials inside Flying Together, because forum explanations can vary by contract group and policy updates.

Can my sponsor (employee) link my MileagePlus number to my Passrider profile, and why does that matter?

Yes—pass rider issues commonly come up right after linking (or re-linking) a MileagePlus number, because the linkage controls identity and what the app/site shows you. If the linkage is wrong (wrong MP number, duplicate profile, or mismatched name/details), you may lose the standby booking option in the app or be locked out of Passrider. A common fix reported is having the employee re-submit the correct MP number through Flying Together and then waiting for the change to propagate.

I used to book standby through the United app and now the option disappeared. What happened?

This is often reported after account linking changes, app updates, or policy transitions where certain listing functions move between eRES and the app. If the app no longer shows the standby/pass rider path, it’s usually a sign your account isn’t recognized as a pass rider in that session, or your sponsorship/eligibility data hasn’t synced. Logging out/in, updating the app, and having the sponsor confirm your setup are the most common next steps mentioned.

What should I do if EmployeeRes/eRES is down or the standby list won’t load?

Forum threads often mention intermittent outages where lists fail to display on certain devices (especially mobile browsers). The fastest troubleshooting steps are switching devices, trying a different network, and clearing cookies/cache for the site. If it’s a broader outage, the only “fix” is waiting it out and using alternate official channels (like the app) if your traveler type supports it.

How far in advance should I rely on flight loads when planning pass travel?

Loads change a lot close-in because of last-minute ticket sales, reaccommodation from cancellations, and operational changes. People experienced with standby travel often treat early load checks as “directional,” not definitive, and focus more heavily on the last 24–72 hours. Always build backup flights/routings because your best-looking option today can flip quickly.

What are common mistakes that get pass riders stuck at the airport?

Common issues include listing for the wrong date, misunderstanding cabin/service selections, missing a required check-in step, and assuming a seat map equals actual availability. Another frequent problem is not having a backup routing and arriving too late to pivot when loads collapse. Pass riders also get stuck when their documents (passport/visa) or name details don’t match exactly.

Can pass riders list for premium cabins (like Polaris or Premium Plus), and how does that pricing/service selection work?

Some pass travel materials describe selecting a “service” level when listing (for example, choosing business vs premium economy vs economy) on aircraft/routes that offer those cabins. The service you select can affect service charges and how you’re processed if a premium seat opens or doesn’t open. If you’re unsure, use the official internal guidance your sponsor has access to, because rules and charges can change.

Is there etiquette or dress code for United non-rev / pass rider standby travel?

Many experienced travelers say not to overthink it, but do avoid anything offensive or overly revealing because you’re traveling on a privilege. “Business casual” isn’t always required, but looking neat reduces friction if a gate agent needs to make discretionary decisions. Shoes, clean clothing, and a respectful attitude go a long way.

What’s the smartest way to choose a standby flight when I have multiple options?

Most people compare multiple flights, not just one, and look for the best combination of availability, time-to-departure, and backup options. A flight with fewer “SA listed” can still be risky if it’s prone to misconnects or last-minute demand. Planning a “primary + backup + last resort” routing is the typical experienced approach.

I’m a former United employee (or helping one) and need pay stubs / employment records. What is the most reliable official route?

A commonly cited official route for employment and wage verification is The Work Number (Equifax), which is used by many large employers for verification workflows. United pass travel / employee forums often point people away from random “HR phone numbers” online and toward official verification channels. If the goal is verification rather than internal HR casework, using the verification provider is usually faster than trying to find a direct HR desk line.

How can I contact United Airlines HR by email or phone?

Most true HR support for employees is routed internally through Flying Together / employee service channels. Flyingtogether does have an official email address at [email protected]. For specific HR issues, employees should use the self-service tools on the portal, the United app, o
For IT technical support try 847-700-5800 or 800-255-5801.
For employment and wage verification, a widely used official channel is The Work Number (Equifax) phone line: 800-367-5690, and United’s employer code is often shared as 10209 for verifications. For recruiting/applicant-related help (not employee HR casework), United’s careers FAQ lists [email protected] and a phone number 888-985-7755; use those only for hiring/application questions, not pass travel or internal HR.

What’s the best way to get help when I’m stuck the day of travel and nothing is updating?

If your listing/standby status looks wrong close to departure, the most reliable fix is usually through official channels: the United app tools (if available for your traveler type) and airport agents for day-of-travel list issues. Public United standby guidance indicates some list visibility problems can only be resolved at the airport. For pass riders, it also helps to have your sponsor available, because many corrections require the employee account holder to adjust the profile.
