Surviving a Long-Haul Flight, From Booking to Landing

A flight of ten hours or more can leave you stiff, dehydrated and exhausted, or it can pass reasonably comfortably. The difference usually comes from small decisions made before boarding and during the flight, not from luck. Following a long-haul trip from booking to arrival shows where those decisions matter and what to pack for each stage.

When booking

Choose your seat carefully. Window seats are best for sleeping, since you can lean against the wall and won't be disturbed. Aisle seats make it easier to get up and stretch. Seats near the front of a cabin tend to be quieter, while those near galleys and toilets see more traffic. Seat maps on the airline's website, and independent seat guides, show which seats have limited recline or missing windows.

Consider timing. Overnight flights that line up with your normal sleep time can make it easier to rest and adjust to the destination.

Weigh the cost of an upgrade. Premium economy offers more legroom and recline for a smaller price difference than business class, which can be worthwhile on very long routes.

The day before

Check in online and confirm your seat.
Download films, podcasts, books and offline maps, since in-flight Wi-Fi can be slow or costly.
Charge your phone, headphones and a power bank. Power banks must travel in carry-on luggage, not checked bags.
Choose comfortable, layered clothing that won't dig in when you sit for hours, along with soft socks and slip-on shoes.
Start shifting your sleep schedule slightly toward the destination time if the time difference is large.

What to pack in your personal item

For sleep: an eye mask, earplugs or noise-canceling headphones, and a supportive neck pillow.
For comfort: a light scarf or sweater, since cabins can be cool, and compression socks if you are at higher risk of blood clots.
For hydration and skin: an empty refillable water bottle to fill after security, lip balm and a small moisturizer, keeping liquids within carry-on limits.
For hygiene: a toothbrush and travel toothpaste, face wipes and a change of underwear and top, which helps if luggage is delayed.
Essentials: medications in original packaging, travel documents, chargers and snacks.

At the airport

Walk around before boarding rather than sitting at the gate, since you will be seated for hours. Eat a light meal, and fill your water bottle after security. If you have lounge access, a shower before a long flight can make a surprising difference.

The first hours on board

Set your watch and phone to destination time and try to follow that schedule for eating and sleeping. Stow everything you won't need so you have as much legroom as possible, and keep a small pouch with essentials such as earplugs, lip balm and headphones within reach. Cabin air is dry, so drink water regularly. Alcohol and large amounts of caffeine can dehydrate you and disrupt sleep.

The middle of the flight

Keep moving. Long periods of sitting slow blood flow in the legs. The US Centers for Disease Control and Prevention advises long-distance travelers to get up and walk occasionally when it is safe to do so, and to flex and stretch the legs and feet while seated. People with risk factors for blood clots, such as previous clots, recent surgery, pregnancy or certain medications, should talk to a doctor before flying, who may recommend compression stockings.

Rest when it fits your new time zone. Recline your seat a little, use your eye mask and earplugs, and fasten your seatbelt over your blanket so crew won't need to wake you during turbulence.

Eat lightly. Smaller meals are easier to digest while sitting, and you can bring your own snacks if airline meal times don't match your plans.

The last hours

Freshen up before the breakfast service rush: brush your teeth, wash your face and change into a fresh top. Drink water, and stretch before landing. Fill in any arrival forms the crew hands out.

After landing

Get outside in daylight if you arrive during the day, since light is one of the strongest signals for resetting your body clock. Try to stay awake until a reasonable local bedtime, and keep the first day's plans light. A short walk, a shower and a simple meal are often the best ways to recover.

Traveling with a layover

If your journey includes a long connection, use it to reset. Walk the terminal, stretch, and find a quiet seat or rest area. Some airports have showers, sleep pods or day rooms that can be booked by the hour. Keep your boarding passes and passport together, check that your next gate hasn't changed, and leave plenty of time if you need to pass through security or immigration again.
