Notice
CTA web services will be intermittently down Wednesday, March 11, 2026, between 6 p.m. and 10 p.m. (ET) for preventive maintenance. This ensures the ongoing protection of the CTA data and systems. If you are planning on submitting an Air travel complaint form online, we recommend doing so before or after this time period. If you choose to submit a form during the server maintenance period, there's a risk that the information may not be received properly. Please note that you will receive an email confirmation if your form is submitted successfully.
Travel doesn’t always go as planned.
This section will help you understand what to expect when issues happen and what you can do. If your flight gets delayed or cancelled or if your baggage is lost or damaged, know what you need to file a claim with the airline.
