Expect some tough going today if you are flying United to/from/through Chicago O’Hare. The check-in system is not operating and United is doing manual check in for flights. You can imagine the mess. This could also cause delays throughout the United system so patience will be required today.
From United’s website as of 7am PDT:
We are currently experiencing some delays and cancellations due to an airport check-in system issue at Chicago O’Hare International Airport. We advise customers to check in on united.com, confirm the latest information on their flights, and allow extra time at the airport. We apologize for any inconvenience, and we are working to fix the issue as quickly as possible.
