IAD with the archaic people movers is just a place to be avoided.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

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

I would have liked an opportunity to move to a different seat ( even would have checked in my hand luggage)as I had health issues where I didn't have to clamber over the passenger next to me to for toilet use/ movement [ She was a highly unpleasant neighbor to sit next to]. In addition, I found that my European phone plan had run out of data and so I was not receiving emails from yourselves on airport wifi to be able to check in online and verifications difficult as did not accept the ticket number I had. I asked for an extra blanket but was told there was none. Then I saw other passengers receiving them. I couldn't eat the food and asked for snacks : Stewardess said " on the way" but they did not bring. The best bit was the check in process in Lisbon. Very efficient. However, I did not understand why we had to collect our bags at Washington then go through customs again. It was not explained. I also with my leg and health issue had approximately mile walk to the gate ( which then changed) . There appeared to be no moving walkways or help provided.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

We had a very long diversion and our food voucher didn’t work because the restaurants were closed

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

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

1 hour late No hot drinks No restroom in the back of the plane

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.

Flight was cancelled last minute due to Air Canada strike leaving us stranded and having to stressfully find a way home that cost hundreds of dollars in excess cost added to the trip. Having just experienced our mother's funeral service, this was not a good way to end our trip.

Biggest problem for me is that I am Star Alliance Gold and they were not able to give me access to to Maple Lounge because of some computer glitch . It was management by information system. She could clearly see my status and still would not give me access because the computer woudl not let her. She should have override that be attentive to a customer and figure rhat out later

Horrible, experience, 5 hours delay, they changed gates 3 times, the last one we had to wait for 1::30 hre for the door to open to get to that gate. 0 apologies from Air Canada, they don’t care at all about their passengers

I had a very disappointing experience with customer service. I was suffering from a severe viral infection that included a rash and persistent cough, leaving me unable to even sit upright. Given the circumstances, I requested travel credits from Canada Air, explaining the potential health risk to others onboard. However, the airline showed no concern for my condition and stated they were not in a position to make decisions based on health considerations. Despite my illness, I received no support or flexibility. Ultimately, I chose to forgo my flight due to their lack of responsiveness. It’s unfortunate that airlines like this operate without prioritizing passenger health and safety.

My return flight experience was one of the worst times I have had traveling anywhere this year. Not because of the flight. It was because there was not enough time allocated to deplane, go through U.S. Customs and U.S. Security to get to the gate for the connecting flight to Boston which I missed, There was well less than an hour between my landing in Montreal from Prince Edward Island to my connecting gate. I even called Air Canada on the morning of my return and noted my concern over the short layover time, not more that 45 minutes. The initial flight was four minutes late. I was seated in the rear of the first aircraft, and it took at least 20 minutes to deplane. The U.S. Customs was a considerable distance from the gate at which we landed. The need for double security seemed unnecessary and redundant. The distance from the security to my gate was again fairly great, and the wrong gate number was listed on my boarding pass. The agent I approached at the flight that was going to Newark, New Jersey was too busy to answer my question as to what gate was for Boston. When I got to the right gate, they had just closed the door to the aircraft even though I arrived a minute late. If I knew the distance to Customs and from Security to the gate, I would have asked for a seat on the next available flight which was 4:30 pm. When I made my call at 6:00AM that morning. When I asked the agent at the Boston gate, he said that the 4:30 flight was already “OVERBOOKED!” I was put on an 8:30 PM flight and didn’t get home until MIDNIGHT. I then had to care for a barnful of hungry animals and didn’t get to bed until 2:00 AM.

From Montreal to Cincinnati the flight was perfect! Flight free and everyone was perfect and a pleasure to travel with. But from Casablanca to Montreal the flight crew were quite cold, unhelpful, also seemed to scold many passengers instead of simply educating or instructing them. There were a couple for sure I could describe but not name… i was really shocked bc my experience w air Canada is typically a good one at the very least. It seemed something was very much so I’m the air w the crew. The two older lady crew members and the male were amazing but the younger lady crew members w the exception of one were very clique-y and snarky, sassy

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.

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.
