As someone that enjoys a drink as much or more than the next guy (and is also frugalish), the fluids rules for flying were a huge bummer for me because it was my practice for morning flights to build myself a nice big bloody mary in a disposable bottle for consumption as I passed my way through the security apparatus and inevitable downtime before the flight. Rather a good deal compared to the pathetic offerings for top dollar otherwise available to travelers. Which brings me to my travel tip: Minis (the tiny little liquor bottles) happen to fit into your TSA quart sized baggie and are perfectly legal to take through security. A bottle of OJ on the far side of the line and you’re in screwdriver heaven. Although, please be discrete as the US still has insane open container laws. Which brings me to my story: Not long after I figured out this loophole, I tossed my baggie full of minis in the x-ray bin and the TSA screener looked at them and gave me a broad grin and said, “Now there’s a man ‘at knows how to fly.” To which I could only grin and nod in agreement.
The article goes on:
Now, since America’s Transportation Security Administration (TSA) hates fun and merriment and America’s airlines probably don’t want you bringing your own drinks on board when you could be buying from them, it’s important to be discreet about this travel tip. Don’t bring 20 minis on the plane, get drunk, try to open the door mid-flight, and ruin it for everyone else. As they say in the adverts, please drink responsibly.
*In some countries, it’s more strict. Under Canadian law, the aircraft operator must provide the alcohol, in addition to serving it. You cannot provide your own for on-board consumption. In the US you can’t self serve. You have to give the bottle to a flight attendant and she will serve it to you. You probably won’t have any problems as long you are discrete.
