For waiver-eligible itineraries, we recommend that you reschedule your travel as soon as possible.

If your flight has been canceled, you may already have been rebooked on another flight. Please visit the My Itineraries page to see if you have been rebooked.

If you have not yet checked in for your flight and you have not been automatically rebooked, you may be able to reschedule your travel through My Itineraries. To do so, select View/Modify next to the impacted itinerary and click the "Change Itinerary" button.

If you have already checked in for your flight, you must cancel your check-in before trying to rebook through My Itineraries. You may cancel your check-in through EasyCheck-in Online
