Passenger Reports

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

First-time passenger · January

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 · December

Fly this route pretty regularly for work. Most of the time it's smooth — January was completely fine, not a bump worth mentioning.
