You're ordering complicated drinks. Most airlines don't have set limits for how much you can drink or what you can order, but it's important to remember that the flight attendants are there to keep you safe, not be your personal bartender. If you do want to enjoy a few drinks, keep your order as simple as possible.

While there is no "hard" universal law, most airline policies in 2026 limit you to buying two alcoholic drinks at a time per person. This "Two-Drink Rule" is designed to allow flight attendants to monitor passenger sobriety and prevent disruptive "air rage" incidents. If you are in a premium cabin like First or Business Class where drinks are free, the same rule generally applies; the crew will serve you one or two drinks and then check back later. It is a critical "pro" tip to know that it is a federal offense (under FAA and international regulations) to consume your own alcohol on a plane; you can only drink what is served to you by the crew. This allows them to "cut you off" if they perceive you are becoming intoxicated. If you are traveling as a group, the crew will likely insist on seeing each person before handing over multiple drinks to one individual. Being polite and hydrated is the best way to ensure the service continues throughout your flight.
