Flying at 38,000 feet, the aircraft encounters the strongest bumps roughly 2–5 hours into the flight. This is clear-air turbulence — no clouds, no visual warning — which makes a pre-flight forecast especially valuable.

The route is served by Qantas, British Airways on Boeing 787 aircraft, with flights typically cruising at 38,000 feet over a distance of 8,862 miles (7,700 nautical miles).

Passenger Reports

Moderate turbulence crossing the jet stream — the kind where you're glad you kept your seatbelt on. Lasted about 30-40 minutes, then smoothed out. I've had worse on transatlantic routes.

Frequent flyer · November

Rough patch over the Atlantic in January — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.

Business traveler · January

More turbulent than I expected. The mid-Atlantic section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.
