Rebooking airline tickets is the process of moving a passenger from the original itinerary to a new one, either at the passenger’s request (voluntary) or because the airline disrupted the trip (involuntary).
The two paths use different fare rules, different endorsements, and different ADM (Agency Debit Memo) exposure. Voluntary rebookings follow the fare’s own change rule, apply the current market fare difference, and add a change fee where the fare allows. Involuntary rebookings follow the airline’s IRROPS policy, usually protect the original fare, and require the correct endorsement in the ticket.
Every rebooking updates the PNR, reissues the ticket, and re-links any ancillaries. Missed steps become chargeback risk.
Common questions
Is rebooking airline the same as reissuing the ticket?
Not quite. Rebooking updates the flight segments in the PNR. Reissuing generates a new ticket number that reflects the new fare, taxes, and any additional collection.
Who pays the fare difference on an involuntary rebooking?
The airline absorbs the difference on a same-fare-class reroute. If the passenger requests a different cabin or routing, the agency collects the difference.
