Now Chase Southwest Airlines Plus Visa is offering 50K points (=$833 Wanna Get Away fare). You may sign up both personal and business cards and get 100,000 points! The Plus Card carries a $69 annual fee which is NOT waived and offers 3,000 anniversary bonus points (=$50 value), while the Premier Card carries a $99 annual fee but offers 6,000 anniversary bonus points (=$100 value) and tier point earning opportunity. That is why in our review, we recommend the Premier Card over the Plus Card. However, for the signup offer, the Plus Card is the better card to have since you pay $30 less for the 1st year.
