Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Business class seats felt very cramped compared to other airlines.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Both my flight where delayed Had 25min to make it to my transfer flight

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .
