The post 10 Things You Shouldn’t Eat or Drink Before and During a Flight first appeared on Crafting Your Home.
A flight can already test a traveler’s patience. Crowded airports, security lines, limited legroom, long waits, and hours spent sitting in the same position can make it worse.
The last thing many passengers want is to make the journey harder with a food or drink choice that leaves them feeling uncomfortable before they even reach their destination.
Flying does not make ordinary foods dangerous for most people. However, aircraft cabins are pressurized to an altitude equivalent of roughly 6,000 to 8,000 feet, and cabin humidity is often much lower than normal indoor environments.
Those conditions can make gas, thirst, indigestion, and fatigue feel more noticeable for some travelers.
That is why many experienced flyers think carefully about what they eat before and during a flight. No airplane meal works for everyone, but passengers sensitive to bloating, reflux, caffeine, alcohol, or heavy meals may find a few simple choices make a long journey easier.
Here are 10 foods and drinks travelers often reconsider before boarding.
Carbonated Drinks If You Are Prone to Bloating
A cold soda or sparkling water can seem like the perfect refreshment before takeoff. For some travelers, however, the bubbles can create discomfort during a flight.
At cruising altitude, gas in the digestive system can expand. The Aerospace Medical Association notes that intestinal gas can expand by about 25% at a cabin altitude of 8,000 feet and advises travelers who are sensitive to bloating to limit gas-forming foods and carbonated drinks shortly before flying.
This does not mean everyone needs to avoid fizzy drinks. Many passengers can enjoy them without any issue.
But if you already know sparkling beverages make you feel bloated on the ground, a flight may not be the best time to experiment.

Very Salty Snacks That May Leave You Feeling Thirsty
Airports are full of convenient salty snacks: chips, pretzels, salted nuts, and crackers. They are easy to carry and simple to eat, but some travelers find that very salty foods leave them feeling thirstier or more uncomfortable during flights.
Aircraft cabins are naturally dry. Cabin humidity is commonly around 10% to 20%, which can contribute to dry eyes, throat, and nasal passages.
A small bag of chips is unlikely to ruin a trip, but eating several salty snacks during a long flight may not be the best choice for travelers who want to arrive feeling refreshed.
Foods That Commonly Cause Gas
Some foods are healthy choices on the ground but may not be ideal right before sitting in a small airplane seat for several hours.
Beans, lentils, broccoli, cabbage, onions, and other fiber-rich foods can cause gas for some people. During a flight, lower cabin pressure can make that gas expand, causing bloating or abdominal discomfort to feel more noticeable.
The issue is not that these foods are unhealthy. It is simply about timing. A meal that works well before a normal day may not feel as comfortable before a long-haul flight.
Alcohol on Long Flights
An airport drink or a glass of wine with an airline meal can feel like part of the travel experience. However, alcohol may not always be the best choice for passengers hoping to arrive rested and comfortable.
Cabin air is dry, and alcohol can leave some travelers feeling more tired, lightheaded, or less refreshed—especially during longer flights. The CDC notes that staying hydrated during air travel is reasonable, although there is no direct evidence that drinking extra water or avoiding alcohol specifically prevents travel-related blood clots.
For some passengers, alcohol also makes it harder to sleep well during overnight flights.
Too Much Caffeine When You Need Rest
Coffee, tea, and energy drinks can be useful for early departures, long layovers, or exhausting travel days. The problem comes when caffeine works against your travel plans.
A large coffee before an overnight flight may make it harder to sleep. An energy drink late in the journey may leave some passengers restless as they try to adjust to a new time zone.
The Aerospace Medical Association includes limiting alcohol, tea, coffee, and caffeinated drinks as part of general hydration guidance for air travel. The goal is not to avoid caffeine completely. It is to think about timing.
Heavy, Greasy, or Oversized Meals
A large fried meal before boarding may sound satisfying, especially after spending hours at the airport. But a very rich meal can feel uncomfortable when you are about to sit in a narrow seat for several hours.
Travelers who are prone to indigestion, reflux, or motion sickness may prefer a lighter meal they already know works well for them.
The issue is not that fried food is automatically bad. It is that feeling overly full can make a long flight more difficult. Choose a familiar meal that leaves you satisfied without making you feel uncomfortable before takeoff.
Strong-Smelling Foods That Affect Other Passengers
Some food choices are not about personal comfort, they are about the people sitting nearby.
Airplane cabins are shared, enclosed spaces, so strong smells can travel quickly. Seafood, pungent cheeses, heavily seasoned takeout, and meals with strong aromas may be unpleasant for nearby passengers.
A meal that smells normal at a restaurant may become much more noticeable inside a packed aircraft cabin. Consider saving strongly scented foods for the airport or your destination.
Messy Foods That Are Difficult to Eat in a Small Seat
A meal that works perfectly at home can become frustrating on an airplane.
Foods with dripping sauces, multiple containers, or ingredients that require a lot of preparation can be difficult to manage on a small tray table. Turbulence, limited space, and nearby passengers can quickly turn a simple meal into an awkward situation.
Experienced travelers often choose foods that are easy to hold and eat without creating a mess. Wraps, sandwiches, fruit, crackers, nuts, and neatly packed snacks are usually easier to manage while flying.
Sugary Snacks That May Not Keep You Satisfied
Candy, pastries, cookies, and sweet drinks are common airport purchases because they are convenient.
However, sugary snacks may not keep some travelers satisfied for long during a lengthy journey. A quick treat can be enjoyable, but it may not provide the staying power many passengers need during long flights.
This does not mean travelers need to avoid desserts completely. If possible, choose snacks that combine carbohydrates with protein, fiber, or fat, such as fruit with nuts, cheese and crackers, yogurt, or a simple sandwich.
Food or Drinks You Do Not Trust
Food safety matters everywhere, including airports and airplanes.
The CDC advises travelers to be careful with food and drinks that may have been improperly cooked, stored, or handled. Choosing fully cooked food served hot, or sealed beverages and packaged snacks, can be a practical choice when food handling is uncertain.
This does not mean passengers should assume airplane food is unsafe.
The same common-sense rules apply in the air as they do anywhere else: avoid items that appear improperly stored, questionable, or unfamiliar if you are concerned. Bring familiar snacks or choose foods you know you tolerate well.

What Experienced Travelers Often Choose Instead
Passengers do not need a strict airplane food plan to have a comfortable flight. A few simple habits can make the journey easier:
- Drink water regularly in dry cabin air.
- Choose foods you already know your body handles well.
- Avoid eating until you feel overly full before boarding.
- Bring simple snacks for delays or limited food options.
- Consider caffeine timing, especially before overnight flights.
- Limit foods that personally trigger bloating, gas, or stomach discomfort.
- Be considerate of nearby passengers when choosing strong-smelling foods.
