16. Free Airline Tickets
If you earn 110,000 points on Southwest, you can get a Companion Pass to fly a family member free for a year! If you apply for a Southwest Plus and Southwest Premier credit card, they will each earn you 50,000 points. (Don’t apply for both at the same time.) Refer a few friends or start charging your regular household bills on them and—voila!—free tickets for your Disney vacation!
