Apply for a Southwest Rapid Rewards Chase Visa card and receive 8 Rapid Rewards credits plus 8 Bonus Rapid Reward credits (enough for your first free round trip flight) and earn a $49 account credit after your first purchase (to offset the $59 annual fee).
There is an annual $59 fee but with your first purchase you get back $49 credit on your statement. This card is a Visa Signature Card which has more benefits than your typical Visa card.
