I just earned my 15th and 16th credits in the Southwest Rapid Rewards program, earning me two Rapid Reward vouchers, and they kindly sent me a friendly letter that included my drink coupons. As I opened it up, I noticed the letter lacked the thickness normally associated with the drink booklet inside. Over the years, the vouchers have gotten thinner and thinner, so I wasn’t too surprised.
It turns out that nowadays the four vouchers are integrated into the letter itself, rather than as a standalone booklet. I also saw that the drink coupons had an expiration date set one year into the future and included my name and partially redacted Rapid Rewards number. I don’t know if this is to prevent people from selling their vouchers on eBay (you can get about a dollar a piece for them) or some other kind of fraud.
Here are the new Southwest Drink coupons:

The booklets get smaller and smaller but the drinks are still free!
