A seldom discussed benefit while flying Southwest is free premium drinks days on Southwest designated holidays. All guests onboard a Southwest flight on the designated dates are offered one complimentary premium beverage, including alcohol. This benefit is rarely announced over the loud speaker and often requires a reminder to the flight attendants.
There are four coming in the next two months that hopefully you can take advantage of.
Keep in mind that people who fly Southwest are probably more fun and friendly than your airline so if you are new to the Southwest, don’t be hesitant to ask your neighbors to use theirs if they aren’t choosing to use the benefit. 😉 Cheers.
