I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

Delay and keep changing gates. I have to run around from B to C then to E.

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

Liked nothing. As per previous segment it was delay delay delay.

Basics were there, but a 5:15 flight with almost no food ans no entertainment, it is quite long.

Extremely uncomfortable sitting in a small space for 2 hours, especially for older people. Understood it was circumstantial.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

We left really late. Things that were out if anybody’s control I guess.

Excellent as always. Service was excellent and fully bilingual. Cannot complain .Will travel again. Always have and will continue. Highly recommended.

I checked a bag and there was only one agent to assist all customers with any issues.

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

The flight left over 2 hours late and caused me to miss my connecting flight. Consequently, I missed my cruise ship out of Barcelona. The cost associated with this miss was as follows: Airfare to Sicily Italy to get on the ship TWO days late - $232.30 Taxi from Airport to hotel $35 Dinner at hotel $38 Hotel in Barcelona - $208 Taxi from Sicily to hotel $70 Hotel in Sicily - $148 Prorated time missed on cruise $ 1,143

Made me check my carry on and then lost it,

The flight ran out of hot meals for the back half of the plane and gave us tuna sandwiches. Not okay, these flights cost too much to short us the experience!

This was a bare-bones flight on a small plane. I chose it for the good fare and the fact that it was nonstop. No entertainment and just beverage service were fine on this short haul.

Our plane was so cramped that I couldn’t fit my bag below my feet and my knees were pressed against the seat in front of me. For a 45 minute flight, We sat on the runway for over an hour before returning to the gate to wait for another 2 hours. We arrived over 4 hours late, uncomfortable and tired.

Being forced to listen to commercials before and after takeoff, being charged for every little thing, in flight entertainment that doesn’t work, on and on.
