Troubleshooting United Issues
Use the United app during web outages
The United app (iOS/Android) routes through different load balancers than united.com. It often continues to work for check-in and boarding passes when the main website is down.
Airport kiosks are always available
United kiosks at airports connect to reservation systems independently of the public website. Check in at a kiosk even during major website outages.
Star Alliance codeshares check in elsewhere
If your UA-coded flight is operated by Lufthansa, ANA, Air Canada, or another Star Alliance partner, you must check in on the operating carrier's website — not united.com.
Use your email confirmation as your travel document
Your United booking confirmation email contains your e-ticket number. This is a valid document regardless of website availability — screenshot it before traveling.

What happened during United's 2015 ground stop?
In June 2015, United Airlines experienced a major system outage that caused a nationwide ground stop lasting about an hour, delaying hundreds of flights. The cause was a corrupted network router file that disrupted their reservation and operations system. This was a significant IT failure that highlighted airline dependency on centralized IT systems. United has since upgraded its infrastructure, but IT outages remain a risk for all major carriers.
