Most people get excited seeing the mini bottles of alcohol on their flight, but sometimes drinking can get carried away, even on an airplane. If a flight attendant thinks that you're getting a bit too buzzed, she can cut you off, no questions asked. It is because getting intoxicated on a plane is actually illegal! Flight attendants are forbidden from providing more alcohol to passengers who are already drunk. And if they are caught doing so, they can face big repercussions.
If you are intoxicated on a plane and cause a major disturbance, you can face criminal charges and a lengthy federal prison sentence. It's also good to know that because of the changing cabin pressure, each glass of alcohol can affect you much more strongly than it would on land.
