Long-haul flight survival guide

Arrive with time to spare, but not four hours. For a long-haul international departure, two to three hours before take-off covers check-in, bag drop and security at most large airports; smaller ones need less, and hubs at peak times need more. If you are connecting, the airline's minimum connection time is the number to beat, and it assumes an on-time arrival.

Once through security, buy water or fill a bottle at a fountain, eat a real meal if the flight leaves at an awkward hour, and charge everything. Airport food is usually better than airline food and often cheaper than the onboard snacks. Board last if you have an assigned seat and no overhead-bin anxiety; board early if you need bin space.

Keep the essentials on your body or in a small bag you never check: passport, wallet, phone, charger, medicine, and a pen for landing cards. Everything else can go in the overhead bin.

Cabin air is dry and pressurised to roughly the altitude of a 1,800-2,400 m mountain, so you lose water faster than you notice and alcohol hits harder. Aim for about a glass of water every hour you are awake, and treat alcohol and coffee as optional. Salty airline meals make it worse; eat the protein and vegetables, skip the bread roll if you are bloated.

Move. Stand up, walk the aisle, and do ankle pumps and calf raises in your seat every couple of hours. This is the practical defence against swollen legs and, on very long flights, against clots. Compression socks help and take almost no space. If you have a history of clots, are pregnant, or have recently had surgery, ask your doctor before flying.

Sleep on the destination's schedule. If you land in the morning, sleep the first half of the flight and stay awake for the second. If you land at night, stay awake as long as you can and sleep the last stretch. Earplugs, an eye mask and a neck pillow do more for sleep than any seat upgrade you cannot afford. Noise-cancelling headphones are the single best-value item for most people.

Entertainment and screens: download films, podcasts and maps before you fly, because onboard Wi-Fi is often slow or paid. Charge from a power bank if your seat has no working outlet. Keep the phone in airplane mode unless you have bought a roaming plan; accidental data charges on a long flight are common.

Long-haul fares swing widely by route, season and how far ahead you book. As a rough 2026 estimate, a US East Coast to Europe round trip in economy sits in the USD 500-900 band, US to East Asia in the USD 800-1,400 band, and Europe to Australia or New Zealand in the USD 900-1,600 band. Peak summer, Christmas and school holidays push these up sharply; booking 2-4 months ahead is usually cheaper than booking 2 weeks ahead, though last-minute deals exist on quiet routes.

The extras add up. Seat selection is often USD 20-80 per leg, a checked bag USD 30-75 per leg on carriers that charge for it, and an upgrade to extra legroom USD 50-150. On a family of four, that can be more than the fare difference to a better airline. Compare the all-in price, not the headline fare.

Time: a nonstop from New York to Tokyo is around 14 hours eastbound and 12-13 westbound; London to Sydney is around 24 hours with one stop and 20-22 on the nonstop routes that exist. Add 2-3 hours at each end for airport and transfers. A one-stop itinerary usually adds 3-6 hours of total travel over a nonstop, and a two-stop adds more.

Overbooked flights: if you are bumped, ask for the written terms and the compensation the airline owes you before agreeing to anything. Volunteers usually get more than people who are denied boarding involuntarily. In the EU and UK, denied boarding on an eligible flight triggers fixed compensation; in the US, the Department of Transportation sets bumping payments. Ask for cash or a transferable voucher, and get a confirmed seat on the next flight in writing.

Cancellations and long delays: EU261 and UK261 cover flights departing the EU/UK and flights on EU/UK carriers arriving there, with fixed compensation after a threshold delay unless the cause is extraordinary. US rules do not require cash compensation for delays, but do require refunds when the airline cancels or significantly changes a flight and you choose not to travel. Keep every receipt for meals, hotels and transport.

Lost or delayed bags: file a Property Irregularity Report at the airport before you leave, keep the reference, and claim essentials. Most airlines reimburse reasonable interim expenses for delayed bags; the Montreal Convention caps liability per passenger for international flights. If the bag is lost for good, you claim against that cap with receipts.

Medical and mobility: if you need oxygen, a stretcher, a wheelchair or a service animal, arrange it with the airline well in advance and reconfirm 48 hours before. Pregnant travellers are usually cleared to fly to around 36 weeks for a single pregnancy and 32 weeks for twins, but each airline sets its own rule and may ask for a doctor's letter (check).

Children and infants: book seats together, bring a change of clothes for the adult as well as the child, and feed on take-off and landing to help with ear pressure. A car seat approved for aircraft use is safer than a lap for a small child if you have bought a seat for them.

Get light, get water, get moving. Daylight at the destination is the strongest signal for resetting your body clock, so avoid a long nap in a dark hotel room if you land in the morning. Walk outside, eat at local meal times, and go to bed at a normal local hour. Jet lag usually eases within two to four days; the direction that hurts most is flying east.

If your bag did not arrive, keep the PIR reference, buy only what you need, keep receipts, and follow up daily. If your passport is lost or stolen, report it to police and your embassy before you try to fly onward. If you were bumped or delayed, submit the compensation claim with your boarding pass, booking reference and receipts; airlines often reject the first claim, so keep copies and escalate to the national enforcement body if needed.
