Southwest flight change policy allows you to change your Anytime and Business Select tickets up to 10 minutes before departure without incurring a fee. The value of your Anytime or Business Select flight ticket will be converted into Travel Funds if you do not make any adjustments to an existing flight and do not show up for it. You have up to 12 months from the date of purchase to use the Travel Funds. If you paid for your ticket with Rapid Rewards points, the points will be refunded to your account and can be used again later. If you wish to change an itinerary that involves an international flight, you'll need to go through the same steps as before. You won't be charged anything. There will be no change costs, but the fare difference (if any) will be charged.
