New cardmembers of the Southwest Airlines Rapid Rewards Visa Signature card can get up to 16 credits — eight after your first purchase and up to eight more with balance transfers made within the first 90 days. The card offers double Reward Dollars on Southwest Airlines flight and vacation purchases and on Rapid Rewards preferred hotel and rental car partner purchases (this is bucking the trend of several other airlines who have ended double miles for flight purchase). Every year on your cardmember anniversary, you will earn two Rapid Rewards credits. The annual fee for the card is $59 — not waived the first year. Cardmembers will also receive a set of benefits associated with the Signature card including exclusive event access, last-minute dinner reservations, discounts, 24-hour concierge service and no pre-set spending limit. Mention card code 7GX2 if applying by phone at (888) 242-6597.
