Enduring a long flight isn’t exactly what is on everyone’s top ten of fun things to do list. It doesn’t need to be as draining and stressful as you had imagined. Follow these top five preparation tips to surviving a long flight so you arrive at your destination as smoothly as possible.

Stay Hydrated

Most doctors recommend that you drink 64 ounces of water per day, but intake should be upped when you’re traveling. The plane is very dry and your body will feel its effects. TSA’s increasingly tight security does not allow liquids through security, so you will largely be at the mercy of flight attendants for your hydration needs, or you can sometimes purchase drinks or fill empty water bottles at the gate. Avoid alcohol and caffeine, as these are diarrheatics and will dehydrate your body. Stick to water, sports drinks, and organic juices if they’re available.

Bring Snacks

It’s inevitable that during an extremely long flight you’re going to be hungry. Bring convenient snacks with some nutritional value such as granola bars and nuts instead of candy bars and chips. Carbs have been shown to improve jet lag so you’ll want to take advantage of the freedom to carb-load while traveling without feeling guilty.

Upgrade

It might be a little tougher on your wallet but if you in any way can afford to upgrade from coach using flyer miles or by scraping together a little extra then do it. The small perks you get such as getting on the plane first and extra leg room matter even more on long flights. Being uncomfortable for three or four hours might seem bad, but imagine having to endure that for ten or more hours. Splurge for your own sanity if possible.

Bring Your Own Entertainment

Don’t bank on being able to sleep during the flight. It may be ideal, but plans don’t always go as planned. Ensure your carry-on has plenty of things to keep you busy without requiring as much space as the rolling equipment cases that you checked before boarding. Have a set plan whether it’s playing games on your phone or tablet. Make the time go by faster by staying busy instead of constantly checking the time.

Snag the Aisle Seat

If at all possible get an aisle seat so you can get up and stretch, walk around, and have a bit more room. You won’t want to be sitting for the entire flight. You also won’t have to worry about getting trapped by the window due to a sleeping seatmate.

Your mind and body might not be fond of a long-haul flight, but it doesn’t have to be unbearable. Preparing ahead of time is absolutely crucial for your journey.
