Passenger Reports

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

Leisure traveler · May

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

Business traveler · August

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