suspend
To remove the value of an unused coupon from an air ticket, typically so as to allow continuation of the next sectors' travel.
suspend: void an unused airline coupon to let travel continue
In airline ticketing, to suspend means to deactivate or remove the monetary value from an unused flight coupon (sector) within a multi-leg ticket. This allows a passenger to continue traveling on remaining sectors without forfeiting the entire ticket value. The suspended coupon is marked invalid in the airline's system, and its value is typically credited or transferred according to the fare rules and carrier policy in effect at the time of suspension.
Most suspensions occur when a passenger misses a flight, cancels a sector, or needs to skip a leg of a journey. Airlines require suspension to prevent abuse: if a coupon were simply left blank, a passenger could theoretically use it again later or transfer it to another traveler. Suspending it creates a permanent record that the coupon has been taken out of circulation. The process is recorded in the ticket's audit trail and flagged in reservation systems.
Mechanics and restrictions
Suspension authority typically rests with the airline that issued the ticket or the ticketing agent handling the modification. Some fares, particularly deeply discounted, non-refundable, or restricted tickets, may not allow suspension at all; these must be honored in sequence or forfeited entirely. Premium fares and standard economy tickets generally permit suspension with little friction. Suspension requests are logged with a reason code: no-show, passenger request, schedule change, or illness.
The suspended coupon's value does not automatically transfer to a later sector; instead, it is typically held as a credit on the passenger record, subject to the original ticket's terms. Many carriers now process suspensions through automated systems tied to check-in gates or airline websites, replacing the older manual coupon-cutting method. Digital tickets have made the term less literal but the practice essential for revenue control and passenger accommodation.
Suspension differs from refund or rebooking. A refund cancels the ticket and returns cash or credit to the passenger; rebooking moves the passenger to a different flight on the same or later date. Suspending simply stops one coupon from being used, leaving the passenger's remaining sectors active. This distinction matters for accounting, tax reporting, and airline revenue recognition under IATA and ATPCO standards.
