Since the pandemic started you can't drink alcohol on planes, at least in the US (I realize this was happening overseas but I suspect that rule is not just the US). I've heard a flight attendant say it's a $10K fine for drinking on a plane now but I don't have confirmation/sources on that, I just know all US flights include a no alcohol announcement since the start of the pandemic. Vaping is also illegal on planes, having nothing to do with the pandemic, for the same reason as smoking (shared air space).
