Should You Drink Alcohol on a Plane?

Many travelers enjoy a drink during a flight to calm their nerves or celebrate the start of a vacation. But with a recent increase in disruptive passenger incidents, often called "air rage," is alcohol partly to blame? Research shows that drinking at high altitudes affects us differently than on the ground. Let’s look at the unique risks of in-flight drinking to help you decide if skipping that drink is the smarter choice.

A Brief History of In-Flight Alcohol

The first commercial airline, the St. Petersburg–Tampa Airboat Line, launched in 1914. However, alcohol wasn’t served on planes until after the 1940s, when Prohibition ended. During the "Golden Era of Flying" from the 1950s to the 1970s, alcohol was complimentary, much like snacks are today. It became part of the luxurious flying experience.

Except for a temporary pause during COVID-19 mask mandates, alcohol has remained a key part of in-flight service. Though it’s no longer free, it’s still popular and deeply tied to the travel experience.

Can You Bring Your Own Alcohol on a Plane?

Yes, you can bring alcohol in your carry-on or checked luggage if it meets airline rules for size and alcohol content. You can also buy alcohol at duty-free shops or airport lounges. However, you’re not allowed to drink your own alcohol during the flight. All drinks served in the cabin must come from a flight attendant. This rule helps prevent excessive drinking. Flight attendants can also refuse service to anyone who appears intoxicated.

Does Alcohol Affect You Differently in the Air?

Many people say they feel the effects of alcohol more strongly on a plane. While altitude doesn’t change your blood alcohol concentration (BAC), cabin conditions can alter how you feel. At high altitudes, oxygen levels are lower—even in pressurized cabins. This can cause symptoms like a faster heart rate, confusion, or dizziness, which may amplify the feeling of being drunk.

Alcohol also affects your balance and coordination. Combined with the motion of the plane, this can make you feel more unsteady or intoxicated than you would on the ground.

Health Effects of Drinking While Flying

Flying is physically demanding, even if you’re just sitting. Adding alcohol increases stress on your body. Alcohol is processed more slowly in the air, so toxins stay in your system longer. Over time, frequent in-flight drinking could raise your risk of alcohol-related health issues.

Should You Drink on a Plane?

While common, drinking during a flight carries more risks than drinking on the ground. If you’re a nervous flyer, there are other ways to relax—like deep breathing, listening to music, or using the Quitemate app. You can also choose from a variety of non-alcoholic drinks to celebrate the start of your trip.

How Much Is Too Much?

There’s no universally "safe" amount of alcohol for in-flight drinking. If you do drink, follow general moderation guidelines: no more than two drinks for men and one for women per day. But keep in mind that even moderate drinking in the air can have stronger effects.

Risks of Drinking on a Plane

• Increased dehydration: Cabin air is dry, and alcohol is a diuretic, which can leave you severely dehydrated.
• Sleep disruption: Alcohol can worsen sleep quality, especially on long or overnight flights.
• Worse hangovers: Dehydration and slower alcohol metabolism can lead to more intense hangovers.
• Increased motion sickness: Alcohol disrupts your balance system, making motion sickness worse for some people.
• Behavioral issues: Lowered inhibitions and increased frustration can contribute to air rage or conflicts.
• Safety concerns: Impaired judgment may lead to ignoring safety instructions or engaging in risky behavior.

Tips for Responsible In-Flight Drinking

• Set a limit: Stick to one alcoholic drink to avoid overconsumption.
• Stay hydrated: Drink plenty of water or electrolyte beverages.
• Choose non-alcoholic options: Try a mocktail, sparkling water, or juice. Use tools like Quitemate for relaxation instead.
• Eat before or during your flight: Never drink on an empty stomach.

Final Thoughts

Although a drink might seem like a good way to relax or celebrate, the unique conditions of air travel increase the risks associated with alcohol. Opt for hydration, entertainment, or a refreshing non-alcoholic beverage to make your flight safer and more comfortable. Your body—and fellow passengers—will thank you.
