Basic Concepts

You can cancel any reservation before it is ticketed.

For a ticket, you can void, cancel, or exchange:

• Void: Cancel for a full refund within an allowed void period, based on the airline's rules for the market in which the ticket was issued. Generally a ticket can be voided within the same day it was issued, usually up to midnight local agency time. In some instances it may be voided up to midnight of the day after ticketing, or special holiday policies may apply.

• Cancel: Cancel after the void period without rebooking on another itinerary. Depending on the fare rules, canceling a ticket may result in a full, partial, or no refund.

• Exchange: Cancel the original air itinerary on a ticket and issue a new ticket.

These terms apply to how a ticket can be refunded or exchanged:

• Voluntary refund or exchange: The passenger or agency initiates the refund or exchange.

• Involuntary refund: The airline cancels the ticket, such as if a flight is canceled and the passenger cannot be rebooked.
