The three amounts to separate
- 1
Fare difference
Start with the new price. Subtract the value that the airline applies from the old ticket. This amount can apply even when there is no change penalty.
- 2
Airline change penalty
A carrier-imposed amount allowed by the fare rules. Some fares or markets have no penalty; others may still restrict or charge for changes.
- 3
Agency service fee
An agency may charge for its work on the change. This is separate from an airline amount. The agency should state the fee before payment.
A simple example without a price promise
The old ticket may have value while each new flight costs more. You may still owe the fare difference even when the change penalty is zero.
If an agency changes the ticket, it may add a service fee that it stated before payment.
Why the new fare can be higher
- A different booking class is available
- Travel is closer to departure
- Peak-day demand is higher
- The route or airport changes
- The trip length changes a fare rule
- Only a more flexible fare remains
Questions to ask before approving a change
- How much value from the original ticket is being applied?
- What is the fare difference?
- Is there a separate airline penalty?
- Is there an agency service fee?
- Which amount is refundable?
- Will any value remain as a credit?
- When does the reissued ticket arrive?
When the airline changed the schedule
A significant carrier-initiated change can create different options from a voluntary change. Keep the notice and ask the ticket issuer to review involuntary rebooking or refund paths before agreeing to a voluntary exchange.
