Apparently it’s a “travel trend” to enjoy a cocktail at the airport that you haven’t purchased – mix your own drinks before getting on the flight. Here’s one creator’s take on the do-it-yourself airport espresso martini, which involves mixing your own booze with Starbucks.

Espresso martini under $10 – mini vodka, Baileys or Kahlua, or both. it’s the airport, there are no rules. And I ordered a double shot of espresso on ice from starbies

Many airports offer alcohol to go which suggests that you can drink throughout the airport, even at your gate.

And some airlines will gladly serve you the wine you bring on board yourself though generally this is not something offered by U.S. carriers. However you are not permitted to drink alcohol you have served yourself while on board the aircraft.

During the pandemic, when airlines weren’t selling booze on board in coach, people were bringing their own or buying drinks in the terminal to bring on board even though it’s illegal to drink alcohol that isn’t served to you by a flight attendant. Of course that was also back when many of us stayed at home and became day drinkers.

That’s become less of a problem with onboard alcohol restored. Still, alcohol minis fit in your 100ml ziploc freedom baggie that you’re allow to bring through airport security checkpoints with liquid. You can bring your own, though it isn’t advised – at least for onboard consumption. You can pregame in the terminal. And consider stocking up on the minis inflight!

• As an AAdvantage Executive Platinum, I get a complimentary onboard beverage and snack (American rarely offers snacks for sale in coach).
  
• Those seated in extra legroom coach (“Main Cabin Extra”) get free alcoholic beverages.
  
• And I have an AAdvantage Aviator Silver card that comes with a $25 daily statement credit toward onboard food and beverages purchases.

When flying American I could really be racking up the mini bottles. It’s a missed opportunity, to be honest. Why I’m not carrying off several on each flight is a question I should really be asking myself.
