Fly with a friend free for the rest of the year on Southwest Airlines
Southwest Airlines has a new promotion called Heartlanta. The promotion allows you to bring a friend along for free (excluding taxes and fees) as a companion (companion pass) to any city that Southwest flies so long as you leave from ATL and return to ATL.
All you need to do is register for the promotion and then buy and fly three qualifying round-trips from Atlanta before May 17, and you will receive companion pass status through December 31, 2015.
Reminder: Only Rapid Rewards Members with a valid Atlanta area address in their Rapid Rewards accounts are eligible for this promotion.
