Passenger Reports

Totally smooth May flight. The seatbelt sign came on once briefly crossing the ridge but nothing actually happened. Great trip.

Leisure traveler · May

I always expect the worst on longer flights but this one surprised me. Very little turbulence, only a few small bumps on descent. Manageable even for me.

Nervous flyer · November

Was nervous about this flight but honestly didn't need to be. Smooth the whole way, the 1h 10m went by fast.
