Passenger Reports

Totally smooth April flight. The seatbelt sign came on once briefly on descent but nothing actually happened. Great trip.

Leisure traveler · April

Was nervous about this flight but honestly didn't need to be. Smooth the whole way, the 4h 25m went by fast.

First-time passenger · April

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.
