How to Sleep on a Long-Haul Flight

Sleep on a plane will never match sleep in your own bed — but the difference between a fitful few hours and none at all can decide how your first day on the ground feels. The good news is that most of what helps is behaviour and preparation, not gadgets. Here's a practical, substance-free approach.

First, decide whether to sleep

Before worrying about how to sleep, work out whether this is even a leg you should sleep on. The most useful habit on any long flight is to set your watch to your destination as you board and let that clock make the call: if it's night-time at your destination, that's your window to sleep; if it's daytime there, you're usually better off staying awake and saving your sleep for later. Sleeping at the wrong time can deepen jet lag rather than ease it. Our In-Flight Sleep Planner turns your departure time, flight length and destination into a simple timeline showing when to try to sleep and when to stay awake.

Set yourself up before you fly

  • Seat choice. A window seat gives you something to lean on and control over the blind, and it spares you being woken by neighbours climbing over you. If you know you'll need to move around, an aisle seat trades lean-support for freedom. Many travellers find a spot away from the galley and toilets quieter.
  • Arrive without a sleep debt. It's tempting to stay up all night before a flight hoping to "bank" tiredness, but arriving already exhausted tends to make the whole trip harder. Being reasonably rested gives you a better starting point.
  • Pack a tiny sleep kit. A well-fitting eye mask, ear plugs or noise-cancelling headphones, and a neck pillow do more than almost anything else, because they tackle the two biggest obstacles: light and noise.

Build a pocket of night around yourself

Your body takes its cues from darkness and quiet. When it's time to sleep, the aim is to convince your senses it's night even in a humming cabin: eye mask on, window blind down, headphones in, and layers or a blanket to stay warm, since cabins run cool and cold tends to wake you. Reclining a little, keeping your seatbelt visible over the blanket so crew don't wake you for checks, and easing off screens for a while beforehand all nudge you toward sleep. Dimming your own screen and the overhead light removes the bright cues that keep the clock awake.

Time it to your trip. Different routes call for sleeping at very different points in the flight. The In-Flight Sleep Planner shows you where your sleep window falls, and the Recovery Plan puts that flight in the context of your whole adjustment.

Food, drink and the dry-cabin problem

Cabin air is extremely dry, and mild dehydration alone can leave you feeling headachy and rough — easily mistaken for jet lag. Sipping water steadily across the flight is one of the simplest wins. Alcohol is a double trap: it may make you drowsy at first, but it tends to fragment the sleep that follows and adds to dehydration, so many travellers find they sleep better going without. Heavy, rich meals late in a leg can also sit uncomfortably; a lighter approach when you're aiming to sleep is usually kinder. If meal service lands in your planned sleep window, it's fine to skip it and rest instead.

If sleep just won't come

Sometimes it doesn't, and fighting it only winds you up. Rest with your eyes closed still has value — a quiet, dark, reclined rest is more restorative than doom-scrolling, even if you don't fully drop off. Keep the environment sleep-friendly and let sleep arrive if it will. And remember that a single rough flight isn't the whole story: what you do in the first few days on the ground, especially getting well-timed daylight, matters more for shaking off jet lag than any one night in the air.

When you land

However the flight went, resist the urge to crash the moment you reach your accommodation if it's daytime locally. Getting onto the local schedule quickly — daylight during the day, a sensible local bedtime at night — is what resets your clock. If you're flagging, a short nap of 20–30 minutes early in the afternoon takes the edge off without stealing that night's sleep. The Light & Sleep Timing tool gives you the specific light windows for your direction of travel.

For anything you take — including melatonin — consult your doctor or pharmacist. This site does not give medical advice.
