Passenger Reports

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 · April

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

Business traveler · April
