Passenger Reports

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

Leisure traveler · January

Did Toronto to Los Angeles last July and it was genuinely one of the smoothest long-haul flights I've had. Barely any movement the whole way.

Frequent flyer · July

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