There are a few differences between the Southwest Rapid Rewards Premier Card and the Southwest Rapid Rewards Plus Credit Card. However, the most notable is the fact that the Premier version charges $99 per year and gives you 6,000 points on your cardmember anniversary, whereas the Plus version charges $69 per year and rewards just 3,000 points on your cardmember anniversary. The Southwest Rapid Rewards Premier Card also comes with no foreign transaction fees, whereas the Plus version charges a 3% fee on purchases you make outside the United States.
