Can I show customers the rules for changing or cancelling a flight before they book?

Yes, a flight booking API can usually provide change and cancellation rules before the booking is confirmed. This helps your staff and customers understand whether a fare can be changed, whether it can be cancelled, and what restrictions may apply. The information shown depends on what the airline or flight supplier sends through the API.

Some airlines provide clear fare conditions, while others return longer or less detailed rules. A fare may be refundable, partly refundable, or non refundable, and changes may be allowed only before departure or under certain conditions. Any charge, refund, or difference in fare is decided by the airline and may change when the booking is made or when a change is requested.

The portal can display the available rules during the booking process, but it should not promise that every airline will describe them in the same way. Special fares, combined airlines, and bookings with several flight sections can have different conditions for each part of the journey. The final rules attached to the confirmed booking should always be treated as the main record.

Before offering this to customers, check which fare rule details your connected flight suppliers provide and make sure your booking page tells travellers to read them before confirming.
