Can the flight booking API check the fare and seats again before my customer pays?

Yes, a flight booking API can usually check the selected fare and seat availability again before your customer pays. This is important because flight availability can change quickly while the customer is comparing options or entering traveller details.

The final check can confirm whether the flight is still available, whether the fare has changed and whether the same booking conditions still apply. If something has changed, the booking page can ask the customer to review the updated details before continuing. This helps reduce the chance of taking payment for an option that can no longer be booked.

The exact result depends on the airline, the flight supplier and the information returned by the API. Some suppliers confirm availability immediately, while others may still reject a booking after the check because seats were taken at the same time. A fare check also does not guarantee that a ticket will be issued, as ticketing depends on the supplier accepting and confirming the reservation.

Ask glideFares whether your chosen flight suppliers support a final fare and availability check, and confirm what customers will see if the fare changes or the flight is no longer available.
