The booking flow
Step 01
Designate your Companion in your Rapid Rewards account
Log in at Southwest.com → My Account → Rapid Rewards → Companion Pass. Enter your Companion's name and date of birth exactly as it appears on their ID. You can change your Companion up to 3 times per calendar year.
Step 02
Book your own flight first
Search and book your flight normally — with cash or points, any fare class (Wanna Get Away, Anytime, Business Select). The Companion Pass works on all of them.
Step 03
Add your Companion after your booking is confirmed
From your confirmation email or 'Manage Reservations,' click 'Add Companion.' You'll pay only the taxes and fees — roughly $5.60 each way on domestic flights, higher for international.
Step 04
Check in together
Check in exactly 24 hours before departure to get the best boarding position. The Companion gets the same boarding group as you.
