I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

United airlines, mediocre at best. No issues , nothing great . Worked for me

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

The first flight was better in terms of the aircraft.

Seating wasn’t too cramped; I don’t understand how luggage bins get full if there are enough for each person. Shouldn’t there be room for the designated carry-on and personal item for each passenger at their seat? THEN, IF for some reason extra room is available for someone who prefers it, then shifts can occur. I’m simply saying it seems that I should have primary access to the storage bin at my seat and underneath in front of me. It was suggested that I go to the back of the plane to store my carry-on when I paid to have access to the first seat after 1st class. The additional stress and inconvenience could be avoided and I think all passengers and flight crew are interested in guidelines that are fair, clear, and reduce tension.

Upgraded to sit at the exit door so good leg room.

Very good except paying twice for seat selection. Once when I booked and again when I checked in.

The app was great, service was wonderful, everything was quick and easy

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Everything was very good, short delay Toronto to Regina on my return to Canada but not a big deal. Thanks Kayak, Dr. Ian Stewart

In both directions, one of the two flights was delayed in departing. due to mechanical issues (not weather). That tells me that inspection and maintenance is not being done often enough to prevent such from occurring. In the outbound direction, the second leg was delayed and we had to change our plans for after landing, thus missing an expected event. In the return direction, the first leg that was delayed; we had a long enough layover that we were not hurried to make our connection, but others were not so lucky. Comment about this survey process: in the multiple choice answers, there is no option for "Not Applicable"; as we had no food on board, we can't properly answer that question.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Flight was fine, 1st plane was a bit old entertainment, 2nd the display was freezing/ crashing every 30min. We had problems getting at gate and waited 2hr to get a gate in Toronto, then had a 90min mechanical delay at the next departure. Weather was bad and I’m just happy we didn’t get stuck.
