How to sleep on a plane: 9 tips for a long-haul flight

Book a window seat

The window is the best seat for sleeping, for two simple reasons. You have a wall to rest your head against, and nobody wakes you to reach the aisle. The aisle seat, by contrast, exposes you to the trolley, the neighbour getting up, and the aisle lighting.

Avoid the last row (often non-reclining seats, close to the toilets) and the rows just in front of an exit. Book early: the good windows go fast. A tool like SeatGuru flags problem seats plane by plane.

Bring the right sleep gear

Three accessories change everything, and fit in your carry-on. The neck pillow (memory foam, not inflatable if possible) stops your head from dropping. The eye mask blocks the cabin light and nearby screens. Earplugs or noise-cancelling headphones cut the roar of the engines, at 75-85 decibels in cruise.

Add a pair of socks for feet that get cold, and a light scarf that doubles as a blanket. The whole set weighs under 500 grams.

Hydrate, the air is very dry

Cabin air is drier than most deserts, with humidity often dropping below 20%. Dehydration tires you out, dries your throat and disrupts sleep. Drink water regularly, before and during the flight.

Take an empty bottle, filled after security, rather than relying on the small cups handed out. Count on about half a litre every three hours of flight.

Skip the alcohol and caffeine

The free glass of wine seems to help you fall asleep. It's a trap: alcohol fragments sleep, worsens dehydration and hits harder at cabin altitude. You fall asleep fast, then wake up two hours later.

Caffeine stays active for six to eight hours. Cut coffee and tea several hours before your target bedtime. A herbal tea or warm water is a far better sleep signal.

Dress in layers

Cabin temperature varies a lot between flight phases, often between 22 and 24°C but with cold spells. Dressing in layers (t-shirt, thin jumper, jacket) lets you adjust without getting up. You're rarely too warm sleeping, almost always too cold.

Pick loose, soft clothes, never tight at the waist. Comfort beats style for eleven hours in a seat.

Set your watch to the destination

As soon as you board, set your watch and phone to the arrival time. Then eat and sleep by that time, not by the departure one. If it's night at the destination, force sleep even without feeling sleepy.

This mental switch is the first anti-jet-lag move. It starts the adjustment before you've even landed.

Manage light and meals on board

Light controls your body clock. On a flight that lands in the morning, skip the mid-flight meal if you need to sleep, and keep the mask on. On a flight that lands in the evening, stay awake and expose yourself to screen light to hold out until local bedtime.

Don't eat heavy just before you want to sleep: digestion delays falling asleep. A light meal beats a full tray at midnight destination time.

Find a stable position

Recline the seat as soon as it's allowed, even a few degrees: it eases the lower back. Rest your head towards the window side with the neck pillow rather than forward, a position that wakes you the moment your neck gives way.

Fasten the belt over the blanket, visible: the crew won't wake you to check during turbulence. A small detail that protects long sleep phases.

Move before and after sleeping

Staying still for eleven hours stiffens the body and hampers circulation. Stand up once every two to three hours, walk a few minutes, stretch your calves. During awake phases, rotate your ankles regularly.

It's not just comfort: mobility lowers the risk of heavy legs and swelling on long flights. You sleep better in a body that isn't completely seized up.
