There was an incredibly surly flight attendant that ruined the experience

First flight was delayed which resulted in missing our connecting. As a result class was downgraded to economy on a later flight.

Unprepared to rebook a flight of people. Uncommunicative. When I received updates in the app it was well after the announcement in the hold room. Offered a single $12 meal voucher, not enough for a sandwich at DEN, for a 17 hour delay. No one was able to explain their meal or hotel reimbursement policy for this cancellation, just handed a card to call the Help desk. My previous flight went through several delays and was finally cancelled, without explanation. The customer help desk closed while there was a long line. I then waited in line for a gate agent almost an hour while simultaneously on hold and trying to text with a remote Delta agent. Communicating with the text agent was almost impossible; they could not find any flights that got me back to my original city before the following evening. Kept offering itineraries that did not get me back to my origin airport or involved additional layovers. In 50 minutes on hold, never got through to an agent by phone. Finally spoke to one of the gate agents who was able to rebook on a red eye that had only one stop and got me back in the afternoon the next day, rather than late evening. Later by email, Delta offered 10,000 loyalty points for the inconvenience of the cancellation. The crew on the red eye flight were delightful. I don’t remember any food or entertainment on that flight.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

worst flight ever from Delta, it got delayed and kept on delaying..

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Did not get a vegetarian option in 1st class and the video was not working.

United, from whom we bought this code-shared flight, mid-flight canceled our tickets for the rest of our itinerary, without explanation. After long delay they tried to re-issue the tickets, but Air Canada could not find the re-issue. It finally resolved after escalation to several layers of supervisors.

On time. Carry on and personal bag was accommodated on the plane. Entertainment was accessible without bringing own device. Whole can of juice was provided rather than a pour.

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.

The flight was cancelled and they lost my luggage which now 5 days later I still don’t have. They gave me food vouchers that did not work so all in all terrible expy

There should be a visible sign of Air Canada, because I walked all around and I didn't notice where was the desk, I was in a rush for the time because it was very difficult for me to find the D gate.

Older interior meant less luggage storage space. Service was good. I was in business class. I receive better service from other carriers

Great, the item that impressed us. The most was the fact that some of us were gonna have a tight connection and the crew invited those people with the tight connection to stand up and leave the plane early. Great idea and it worked for us

All went smoothly from Miami to Montreal from boarding to arriving to Montreal. Flight left on time and arrived on time.

It was pretty good. It was my first time using the airline I believe but it was a relatively pleasant experience.

Multiple delays and flight cancellations meant that I arrived five and a half hours late at my destination. There was limited communication from the airline. The airline left my checked bag at my departure city and stopped tracking it almost immediately. The airline has made no apparent effort to return my bag despite filing a report, and has provided no communication or ability to check on the status of the bag.

1didnt have wheel chair I ordered wheel chair in my ticket flight

Flight was over an hour late departing and when we got to Montreal there was no gate and so we had to wait on the tarmac for over an hour!!!!!

I like the tv show the seat was ok and the crew was awesome
