A long flight is survived by preparation, not by endurance
Ten hours in a seat is not a test of stamina. It is dry air, immobility, dehydration, noise and a broken sleep schedule. Each of those can be reduced in advance, and together they make the difference between arriving wrecked and arriving tired but functional.
A separate question is what to do on arrival. Time zones hit hardest those who land and go straight to bed at three in the afternoon.
What actually helps
| Factor | What to do |
|---|---|
| Dehydration | Drink water regularly rather than when thirsty |
| Immobility | Get up and move every couple of hours |
| Dry air | Lip balm, moisturiser, glasses instead of lenses |
| Noise | Earplugs or headphones — they also help you sleep |
| Back and neck | Support for the neck and lower back, not just the head |
| Legs | Loose shoes; compression wear if your doctor advises it |
Your seat
Aisle if you plan to get up and sleep in fragments. Window if you want something to lean on and would rather not be woken. Exit rows give legroom but do not always recline and are not always available to children. Choose deliberately rather than taking whatever is assigned.
Sleep and time zones
Start adjusting a couple of days ahead: shift your sleep an hour or so towards the destination. On board, set your watch to the destination and live by it: sleep if it is night there, stay awake if it is day.
On arrival, hold out until the local evening and get into daylight — it does more for the adjustment than any attempt to catch up on sleep during the day.
Food and drink
Heavy food and alcohol worsen dehydration and make sleeping harder. Bring your own snack: on a long flight the gaps between services can be hours, and the trolley does not always arrive when you need it.
With children
A child needs occupation, water, snacks, a change of clothes and an explanation of what is happening. Plan activities by the hour rather than for the whole flight at once: attention runs out faster than the cabin air.
When you are ready to fly
The seat is chosen deliberately, water and snacks are packed, earplugs and something for sleep are with you, devices are charged, documents are to hand, there is a plan for the time zones, and the day after arrival has nothing important in it.
