How do you choose the best flight and seat for a long-haul trip?

Nonstop flights save time and reduce the risk of missed connections and delayed bags. Overnight departures can work well if the timing lets you sleep during the destination’s night.

Aircraft matters too. Newer widebodies like the Boeing 787 and Airbus A350 are designed with lower cabin altitude and higher humidity, which many travelers find more comfortable. For the best rest, a lie-flat seat is hard to beat; see how to choose a business-class seat and our business class vs premium economy comparison.

What should you pack in your carry-on for a long flight?

Keep a small bag at your seat with everything you’ll need in flight, and put the rest overhead. Liquids must follow TSA’s 3-1-1 rule at US checkpoints.

Noise-canceling headphones, eye mask, and earplugs
Layers, warm socks, and a scarf or light sweater
An empty refillable water bottle to fill after security
Medications in original containers, plus a basic toiletry kit
A change of clothes in case your bag is delayed
Chargers and a power bank, following airline battery rules

How do you reduce the risk of blood clots on a long flight?

Long flights slightly increase the risk of deep vein thrombosis (DVT), a blood clot usually in the leg, especially for travelers with existing risk factors. The CDC recommends moving regularly: walk the aisle when it’s safe, and flex and extend your ankles and calves while seated.

If you have higher risk, such as recent surgery, a history of clots, or pregnancy, talk to your doctor before you fly. They may recommend properly fitted compression stockings or other measures.

How should you eat, drink, and sleep on board?

Cabin air is dry, so drink water steadily. Alcohol and caffeine can disrupt sleep and dehydrate you, so keep them modest, especially on overnight flights.

Switch to destination time when you board and eat and sleep accordingly. Request special meals in advance, as airlines usually need notice of at least a day or two. Pack a few snacks in case meal timing doesn’t suit you.

What should you do after you land?

Get outside into daylight, eat on local time, and resist a long nap. Pre-arranged airport transfers remove one more decision after a long night. For a detailed recovery plan, read how to beat jet lag.

Some hubs have arrivals lounges with showers for eligible passengers, a welcome reset before an early meeting. See our airport lounge access guide.

Frequently asked questions

What is the best way to sleep on a long-haul flight?

Sleep during the destination’s night, block light and noise with an eye mask and noise-canceling headphones or earplugs, and dress in comfortable layers. Skip heavy meals and alcohol right before sleeping. In economy, a window seat gives you something to lean on. In business class, a lie-flat seat makes real sleep much easier.

Should I wear compression socks on a long flight?

They can help travelers at higher risk of blood clots, but talk to your doctor first, especially if you’ve had clots, recent surgery, or are pregnant. For most healthy travelers, the CDC’s core advice is to move regularly: walk the aisle when it’s safe and flex your calves and ankles while seated.

What is the best economy seat on a long-haul flight?

It depends on your priority. A window seat is best for sleeping, while an aisle seat makes it easier to stretch and walk without disturbing others. Exit rows offer more legroom but may be colder and have fixed armrests. Avoid seats next to lavatories and galleys, and consider premium economy for extra space.

How early should I arrive for an international flight?

Plan to arrive about three hours before an international departure, especially from busy airports like LAX. That leaves time for bag drop, security, and walking to distant gates. Airlines set check-in and bag-drop cutoffs, often an hour or more before international departures, and missing them can mean losing your seat.

Is premium economy worth it on a long-haul flight?

Often, yes, on flights over eight hours or so. Premium economy offers a wider seat, more legroom, more recline, and usually better meals than economy, at a fraction of business-class prices. It isn’t lie-flat, so if you need to sleep well and work on arrival, business class may still be the better investment.
