This could also be a great time to check your existing cash or award bookings with Southwest, cancel them, and rebook them with the 20% discount.

Best Ways to Book

By using one of Southwest’s co-branded credit cards to book your flights, you could also earn 2x to 4x points spent on your Southwest purchases. These cards also come with other useful perks like anniversary bonus points every cardmember year, EarlyBird Check-In certificates, and more.

Alternatively, we recommend using a credit card that rewards you for airline or general travel purchases.
