Passenger Reports

The mid-Atlantic section was legitimately rough. I was holding on to the armrests. Lasted maybe 40 minutes. One of the flight attendants had to sit down. Not a fun 14h 30m flight but we landed fine.

Solo traveler · November

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

Nervous flyer · March

Rough patch crossing the jet stream in July — drinks went everywhere on the row behind me. Probably 45 minutes of actual turbulence. Nothing dangerous but definitely uncomfortable.
