Documents Needed
6-digit reservation reference or 13-digit ticket number, valid passport for international flights, visa if required, and any necessary health or immigration forms (e.g., Mexico's Online Immigration Form).

International Check-In Rules
Web check-in is available 24 hours prior to departure. Passengers must verify passport and visa details. For some destinations, you may need to fill out an Online Immigration Form in advance. If documents cannot be verified online, you must check in at the airport counter up to 180 minutes before departure.
Group Check-In
Groups of 10 or more passengers on one reservation can access special group travel benefits. All travelers must be on the same flight and travel date. Group check-in may require assistance at the airport counter or via the Call Center.
Troubleshooting
1. 'Unable to check in online' - Often due to passport/visa verification requirements for international flights; proceed to the airport counter. 2. 'Boarding pass greyed out in app' - You may need to complete document checks at the airport before a boarding pass is issued. 3. 'System glitch' - Try clearing your browser cache, using the mobile app, or checking in at an airport kiosk.
