They were fast and I like how they used to entertainment system to play video about the safety.

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Horrible; seating was atrocious - inadequate leg room and seat width tight even for a small individual. Profits shouldn’t be everything!

I flew basic economy, so it was what I expected. Crew was nice though, and flight was quick. Would recommend for flights under 6 hours, otherwise would upgrade to something with more leg room.

Airline staff was good the checkin process was ok but the plane itself was very bad the comfort was worst it was worst and the most stiff 5 hours of my life i felt claustrophobic

Calgary desperately needs a star alliance lounge in the transborder area for United.

Leg room was lacking. Legs crammed into seat in front.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Flight was delayed but reasonable notice and communication was always there for the passengers.
