Southwest Airlines is offering “Double Credit Days” today through May 26.
To be eligible, you must be a member of the airline’s frequent flier program, called Rapid Rewards, but you can join today and still earn the extra credits.
If you already belong to the Rapid Rewards program, you still have to register online to get in on the promotion. If you fly and don’t register, you won’t get the double credit.
Once you are registered, you will earn 2 credits for every flight (4 credits for every roundtrip). If you buy Southwest’s Business Select ticket, which includes perks such as early boarding and drinks, you will get 2.25 credits for shorthauls and 3 credits for longhaul flights.
The trick here is that you must book and complete your travel between now and May 26. It takes 16 Rapid Rewards credits to earn a free Southwest flight.
On Wednesday, Southwest announced that its traffic increased slightly in March, 0.4 percent over last year’s numbers.
