Turbulence on a long-haul flight: what to expect and how to cope
Long-haul flights often cross the jet stream, so a bumpy hour or two is normal. Here is where turbulence usually happens over oceans, why it's safe, and how to get through a long flight calmly.
Ten hours in the air means more time for your mind to worry, and more chances to meet a bumpy patch. On long-haul flights, especially over oceans, some turbulence is normal, and it's no more dangerous than on a short hop.
Practical answer
- Expect one or more bumpy stretches on long ocean crossings, often near the jet stream.
- Check the turbulence forecast for your route to see roughly when.
- Keep your seatbelt loosely fastened whenever you're seated, including when you sleep (over the blanket).
- Choose a seat over the wing for a smoother ride.
- Plan your rest, meals and walks for the calm stretches.
Why long-haul flights get bumpy
Most long-haul routes cross one or more jet streams, fast winds at cruising altitude. Their edges are where clear-air turbulence lives. Westbound flights across the Atlantic or Pacific often fly into the jet stream, eastbound flights ride it for a faster trip, and both can cross its bumpy edges. Read Clear-air turbulence explained.
Pilots plan for this. Before departure, the crew reviews the turbulence forecast for the whole route. In flight, they get reports from aircraft ahead and change altitude to find smoother air.
How to cope on a long flight
- Know the shape of your flight. A bumpy hour in the middle of a 10-hour flight is just that: one hour. Our forecast shows where it's likely.
- Sleep belted. Fasten your seatbelt over your blanket so the crew won't wake you when the sign comes on.
- Use calm stretches for everything else: meals, walks, the bathroom.
- Watch the progress. Seeing the time remaining and where you are on a map makes long flights feel finite.
- Have a bump routine: belt check, long exhale, eyes on the crew, a meditation or film.
What not to rely on
- Alcohol to "sleep through it": it worsens dehydration and anxiety on long flights.
- Constantly watching the seatbelt sign. It means "stay comfortable", not "brace".
Frequently asked questions
Which part of a long-haul flight is bumpiest?
It depends on the weather that day, but bumps are most common near jet streams, often over the ocean, and sometimes during climb and descent through clouds.
Are night flights smoother?
Climb and descent can be smoother at night because the sun isn't heating the ground. At cruise, jet stream turbulence doesn't depend on the time of day.
Is turbulence on a long-haul flight more dangerous?
No. The aircraft is built for it regardless of flight length. Longer flights simply have more minutes when bumps can happen, which is why keeping your belt on matters.
