Passenger Reports

More turbulent than I expected. The on the climb out section was pretty rough — overhead bins rattling, some gasps from other passengers. Died down before landing.

Leisure traveler · May

Moderate turbulence on the climb out — 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 · March

This was genuinely difficult for me. Real bumps for a long stretch on the climb out, seatbelt sign on for what felt like forever. The flight attendants were calm which helped. Got through it.
