Guide Overview: What You'll Need

Total Time: Varies depending on flight duration
Estimated Cost: $10 – $30
Difficulty Level: Easy
Tools Required
- Reusable Water Bottle (at least 1 liter capacity)
Supplies & Materials
- Electrolyte Tablets or Packets optional
- Fresh Fruit or Cut Vegetables for snacks
- Herbal Tea or Low-Caffeine Beverages for drinking
Step-by-Step Instructions
- 1. First, I always pack a refillable water bottle in my carry-on luggage to ensure I have a constant supply of water throughout my journey. I like to choose a bottle that’s BPA-free and can fit comfortably in the seatback pocket or under the seat in front of me.
- 2. Before boarding the plane, I make it a point to drink plenty of water at the airport to get myself hydrated before the flight even takes off. This helps me avoid relying on the limited water servings on the plane and reduces my chances of getting dehydrated during the flight.
- 3. Once I’m on the plane, I avoid caffeine and sugary drinks as much as possible, opting for water or herbal teas instead. These types of drinks can dehydrate me further, which is the last thing I want when I’m already in a dry aircraft cabin.
- 4. To make drinking water more enjoyable during the flight, I add slices of fresh lemon or lime to my water bottle. Not only does it give my water a refreshing taste, but it also helps to boost my immune system and reduce any inflammation caused by the dry air.
- 5. I also make sure to eat hydrating foods like fruits, nuts, and veggies during the flight to help my body retain water. Avoiding salty snacks is also a must, as they can dehydrate me further and leave me feeling bloated and uncomfortable.
- 6. Every hour or so, I get up from my seat to stretch and move around the cabin. This helps to increase blood flow and reduce stiffness, which can also contribute to dehydration. Plus, it’s a great excuse to get some exercise and explore the plane.
- 7. Finally, I always monitor my body’s hydration levels by paying attention to the color of my urine and my overall energy levels. If I’m feeling tired, dizzy, or noticing that my urine is dark yellow, I know I need to drink more water ASAP to get my hydration levels back on track.
Mastering How to Stay Hydrated While Flying

As a seasoned flight attendant, I’ve learned that in flight hydration tips are crucial for a comfortable journey. One of my favorite hacks is to bring a refillable water bottle on board. Not only does it reduce plastic waste, but it also ensures I have a steady supply of water throughout the flight. When it comes to choosing the best water bottles for travel, I look for ones that are lightweight, leak-proof, and fit perfectly in the seatback pocket.
Staying hydrated at high altitudes requires more than just drinking water. I also make sure to munch on electrolyte rich snacks for flying, like nuts or dried fruits, to help my body retain water. And, let’s be real, airplane food and hydration don’t always go hand-in-hand. That’s why I try to avoid salty or heavy meals on board, opting for lighter options instead.
By prioritizing hydration and making a few simple changes to my in-flight routine, I’ve noticed a significant reduction in jet lag. It’s all about finding that balance between rest, hydration, and nutrition. For me, it’s not just about avoiding jet lag with hydration, but also about arriving at my destination feeling refreshed and ready to take on the day. Whether you’re a seasoned traveler or just starting to explore the world, I hope these tips will help you stay hydrated and happy at 30,000 feet!
Electrolyte Rich Snacks for High Altitude
When I’m flying, I swear by electrolyte-rich snacks to keep my energy up. I always stash some dried fruits, nuts, and seeds in my crew bag – they’re perfect for a quick pick-me-up at high altitude. My personal favorite is dried apricots, which are not only delicious but also packed with potassium to help regulate fluid balance. I also love munching on trail mix with a mix of almonds, cashews, and pumpkin seeds – the combination of healthy fats, protein, and complex carbs keeps me going throughout the flight.
Sip Fly Repeat in Flight Hydration Tips
As a seasoned flight attendant, I’ve learned that staying hydrated on a flight is all about balance. I always recommend bringing your own refillable water bottle on board and taking small sips throughout the flight. Avoid sugary drinks and caffeine, which can dehydrate you further. Instead, opt for herbal teas or infused water – I personally love adding a slice of lemon or lime to my water for a refreshing twist.
My crew friends and I also swear by electrolyte-rich snacks like nuts and dried fruits to help our bodies retain water. And don’t forget to eat hydrating foods like cucumbers, carrots, and apples!
