There’s something magical about watching clouds from 35,000 feet up. But let’s be honest—what happens inside the cabin isn’t always so dreamy. Dehydration creeps in. Your stomach rebels. Your skin gets weird. And by the time you land, you’re not feeling refreshed—you’re feeling wrecked.
After too many flights where I either overdid it on salty snacks or forgot to drink enough water, I’ve finally dialed in a long-haul routine that leaves me feeling surprisingly human when I land. Whether you’re traveling for business, pleasure, or just trying to survive a red-eye, what you eat and drink on the plane matters more than you think.
Let’s break down the best hydration, nutrition, and comfort strategies for your next flight—because your body deserves a first-class experience, even if you’re in seat 34B.
Hydration: Your In-Flight Superpower
You’ve probably heard you should “drink lots of water on planes.” But why does it feel so much harder to stay hydrated when you’re flying? The answer’s in the air—or rather, the lack of it.
1. Why Planes Suck the Moisture Out of You
Airplane cabins hover at about 10–20% humidity—about the same as the Sahara Desert. You lose more fluid than normal just by breathing. Add in salty snacks, coffee, or alcohol, and dehydration hits faster than you expect.
Symptoms sneak up on you: headaches, fatigue, dry skin, irritability, and even worsened jet lag. Staying ahead of it is everything.
2. How Much Water You Really Need
A good rule of thumb? One 8-ounce glass of water per hour of flight time. On a 10-hour flight, that’s 2.5–3 liters. Don’t panic—just space it out:
- Start hydrating the day before your trip.
- Sip water at the airport and between meals on board.
- Offset coffee or wine with extra H2O.
I set a subtle timer every hour just to remind myself. It's low-effort, high-reward.
3. Hydration Hacks That Actually Work
- Bring a Reusable Bottle: Refill it after security and ask the crew for top-ups mid-flight.
- Electrolyte Tablets: Add them to your water to help retain hydration and boost energy.
- Infuse It: Lemon slices, cucumber, or a splash of coconut water can make plain water feel more interesting.
- Hydrate Skin Too: Bring face mist or moisturizer to help your skin fight the dryness.
Eating Smart in the Sky
Airline food isn’t known for being... amazing. But you’re not stuck with it. With a little planning, you can eat like a wellness-savvy traveler—even 40,000 feet above sea level.
1. Why Your Taste Buds Get Weird in the Air
At cruising altitude, your sense of taste dulls—especially for salt and sweet. Airlines often overcompensate by loading meals with sodium or fat, which can mess with digestion and leave you feeling bloated.
2. Foods That Fuel Without Fatigue
Instead of heavy meals, focus on snacks and light bites that:
- Keep energy steady: Think whole grains, fruits, and protein
- Support digestion: Include fiber and water-rich foods
- Don’t make you feel gross: Avoid heavy sauces or fried items
Great options:
- Brown rice bowls with lean chicken or tofu
- Veggie wraps with hummus
- Fresh-cut fruit, cucumber, or bell pepper strips
3. Pro Tips for DIY Plane Food
- Pack TSA-Friendly Snacks: Wraps, granola bars, trail mix, fruit, or hard-boiled eggs
- Go Easy on Dairy & Gluten: They can get dicey when you’re seated for hours
- Avoid Super Salty Snacks: They worsen dehydration
- Bring a Few Comfort Foods: Dark chocolate or a homemade muffin can be a mood boost
Supplements That Can Make a Difference
Let’s be clear—supplements aren’t miracle pills. But if you’ve got a long-haul flight and a sensitive system, a few smart add-ons can help you feel more balanced and resilient in-flight.
1. Do You Need Supplements for a Flight?
Not always. But when you’re crossing time zones, eating at weird hours, and breathing dry air in close quarters, they can support your system and smooth the transition.
2. Smart Supplements to Pack
- Vitamin C: Helps your immune system stay sharp in germy planes
- Probiotics: Keep digestion stable despite travel stress
- Melatonin: Helps reset your sleep cycle if you're flying overnight
- Magnesium: Supports muscle relaxation and reduces irritability or leg cramps
I pack a mini “travel wellness kit” with just the basics—it’s small but mighty.
Move or Snooze: How to Avoid the Zombie Zone
Hours in a tiny seat can turn anyone into a cranky, stiff version of themselves. Movement and energy management are essential if you want to walk off that plane like a functional adult.
1. Why Sitting Still Wrecks You
Staying motionless for hours reduces circulation, increases stiffness, and raises the risk of swelling or even DVT (deep vein thrombosis). It also kills your energy.
Even small movements can keep things flowing and help you avoid that heavy, foggy feeling on arrival.
2. Easy In-Seat Movement Tricks
- Ankle Rolls: Do a few sets every hour
- Knee Lifts: Subtle, but they get blood moving
- Shoulder Rolls and Neck Stretches: Undo all that hunching
- Seated Twists: Good for digestion and back tension
3. Keep Energy Up Without Jitters
- Snack Strategically: Choose complex carbs and healthy fats (like almonds or a small sandwich)
- Drink Herbal Tea: Chamomile or ginger is calming and travel-friendly
- Skip the Double Espresso: It might keep you up when you need to adjust to a new time zone
Layover Nutrition and Wellness
Layovers don’t have to mean greasy food courts and sore backs. Used right, they’re a chance to refresh, refuel, and reset your rhythm.
1. Turn Layovers Into Wellness Windows
Instead of just sitting at the gate:
- Walk around to stretch your legs
- Find a lounge with better food and hydration
- Visit a spa, meditation room, or even a nap zone
2. Best Things to Do for Your Body Mid-Journey
- Drink water—yes, again!
- Eat a real meal with veggies and protein
- Use downtime for mental reset—journaling, deep breathing, light reading
3. Upgrade Your Nutrition Between Flights
Airport dining is improving! Look for:
- Build-your-own salad counters
- Sushi or rice bowl vendors
- Protein smoothie stands
I usually grab a veggie-packed wrap and some fruit to-go—it beats the sad sandwich on the next leg.
Real Talk: FAQs About In-Flight Eating and Drinking
Still got questions? Here are the ones I hear all the time (and ask myself mid-flight):
1. Can I Bring My Own Food on the Plane?
Absolutely. Just avoid liquids (soups, sauces) that might flag TSA. Wraps, fruit, and snack bars are perfect carry-ons.
2. What’s the Worst Thing to Eat on a Flight?
Super salty foods, heavy fried meals, and anything gassy (looking at you, broccoli and beans) are best avoided. They don’t sit well in cramped quarters.
3. Is It Okay to Have a Drink?
One glass of wine or beer won’t ruin you—but it’s best to keep it light and sip water alongside. Alcohol dehydrates and can make jet lag worse.
4. Should I Skip Airline Meals?
If they don’t meet your needs, yes. You’re allowed to politely decline and eat your own packed options instead. Just be sure your alternatives are satisfying and safe.

You’ve Got This—Snack, Sip, and Soar
