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

Yes, a flight booking API can usually check the fare again before the booking is completed. This helps confirm that the selected flight, booking class and fare conditions are still available after the customer has chosen an option from the search results.

Flight fares can change quickly because airlines control availability and may update a fare at any time. The final check may return the same fare, a different fare, or a message that the selected option is no longer available. The exact result depends on the airline, the supplier and the information their API provides.

If the fare changes, the booking journey can normally ask the customer to review and accept the updated details before continuing. A fare check does not hold a seat or guarantee the fare unless the airline or supplier supports a separate hold option. Some booking flows may also require another availability check when the reservation is created or when the ticket is issued.

Ask glideFares whether fare checking is available with your chosen flight suppliers, and confirm how your portal will handle changed fares before you start taking live bookings.
