Passenger Reports

Totally smooth March flight. The seatbelt sign came on once briefly over South America but nothing actually happened. Great trip.

Leisure traveler · March

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

Business traveler · September

Did São Paulo to Porto Alegre last January and it was genuinely one of the smoothest long-haul flights I've had. Barely any movement the whole way.
