A question for the experts?

If we were to book our flight early, the price drops, and the airline gives vouchers for the difference. How long are the vouchers good for? Do you have a certain time period to use them up? Just curious. Thanks!

In can vary by airline, so you'll need to check with the carrier in which you plan to buy tickets. Most of the major airlines vouchers are valid for one year from date of issue. Southwest, for example, allows the fare difference to be used only for travel completed one year from the original date of purchase of the original ticket.
