You can legally bring in airline minis on your carry-on past TSA, provided they are factory-sealed and in a quart Ziploc meeting the 3-1-1 rule.
and you can get sloshed at the airport too. I’ve come close on delayed flights.
You can get sloshed at the airport.
Just like you can drive 150 on the highway.
Both equally smart, both have consequences. Getting away with it once doesn't change how dumb it truly is.
Federal law prohibit boarding intoxicated passengers. So, getting sloshed at an airport is a really dumb idea - because the airline can refuse you travel, and they owe you nothing. No compensation.
Federal law also prohibits passengers from consuming their own alcohol on flights.
So, bring your minis, sneak a few on the flight, piss off the flight attendants, get met by the cops, get banned for life on that airline. It's happened before, and following your advice, it will happen again.
Federal stipulates both of those things for safety. Inebriated passengers cannot evacuate an airplane in an emergency. 90 seconds to evacuate the entire airplane is the certification standard for every passenger aircraft. Can't do that with impaired individuals. So, the airlines have a responsibility, backed by federal law, to prevent inebriation in their passengers. It's unsafe.
I just went through this with a young couple flying from EWR to HNL last week. They were probably already a bit under the influence when they boarded. They brought their own booze. Tried to consume it on the airplane. Got belligerent and profane with my crew (a huge mistake) when they were caught. As they sobered up, they apologized and calmed down.
Which worked out better for them. I had already begun the process of coordinating a landing in SFO, and having them taken off by law enforcement. I'm quite serious.
Their big, special trip to Hawaii was about to be canceled by their own stupidity.
If your need for a drink is so strong that you cannot get through a day without getting sloshed, do everyone a favor and stay home.
Getting sloshed at an airport, or on an airplane, is a terrible idea.
