I just got an email from Southwest Rapid Rewards for a chance to enter to win 25,000 Rapid Rewards points. It takes about 30 seconds to enter so you might as well.
Per the rules, they choose four winers every month to win the 25,000 Rapid Rewards points. It was aimed for customers who have birthdays in May or June, but it appears that they send this out every month if you have your birth date registered in your Rapid Rewards profile.
Good luck and maybe one of our readers will win!
