How Do Airline Cancellation Policies Work for Roundtrip Flights?

Airline cancellation policies for roundtrip flights vary by airline and ticket type, impacting customers’ ability to cancel or change their travel plans with fees or penalties.

However, many airlines have waived change fees for specific fare classes, especially in light of the COVID-19 pandemic, to provide greater flexibility for travelers.

  • Refund Process: When a flight is canceled, the refund process may take several days to weeks. Refunds are applied to the original form of payment. Airlines are required to process refunds for canceled flights, but this does not guarantee a refund for unused portions of a roundtrip if only one leg is canceled.

  • Travel Insurance: Purchasing travel insurance can help mitigate financial losses associated with cancellations. Policies typically cover specific events, such as illness or unexpected emergencies, allowing for full or partial refunds depending on the circumstances.

  • Documentation: Travelers may need to provide pertinent documentation or evidence when seeking a refund or making a cancellation. This evidence could include flight confirmation numbers, original ticket purchases, or medical documentation when applicable.
