Hopper is unable to rebook flights in case of cancellation due to weather, mechanical issues, airport delays, and so on. If your flight is canceled, you will need to contact the airline directly to rebook.
In some instances, due to major weather events or similar, airlines may waive change fees for a period of time.
Contact the airline immediately in case of cancellation or delay. If you are at the airport during the cancellation, Hopper recommends calling your airline’s customer service line as well as going to the airline desk in order to rebook.
