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!!

Typical Canadian airline experience. Charger and tray were broken, food was poor quality, and yet you're still paying more than flights with equal to better service than elsewhere globally.

Not enough food option. And not enough advices or information about what we are gonna eat.

my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

7 hour layover was a drag. Free internet on the long leg was great.

From vancouver go calgary nd vice vetsa fligjt was delayed

It was good! Short flight and it was on time!

Staff was nice, helpful, and did all they could. I understand economy seats are bottom of the barrel, but we're crammed in there with others in our row.

Really out of Air Canada's control due to long delay because of mechanical issues. While doing their best, disappointed by their assumption that all passengers have smart phones. Should have communicated food voucher availability at gate area. Late arrival cost me an extra $51 because public transit was not available, Otherwise, feel Air Canada did their best dealing with their challenges. Will likely continue using them in the future.

They canceled my flight, I had to rent a car, drive 14 hours. They tell to go on line for a refund, but only offer $24 for a $210 flight and you can’t get hold of anybody by phone and no help from staff at the airport.

I wish to travel with Air Canada for my next 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

Economy seats always cramped, no meal on international flight, no plugs for electronics, but we got there and cabin crew was excellent.

They were very attentive, polite, professional and great customer service skills.

Business class was not worth the extra charge. Overpriced for slightly larger seat. Nothing special. Small older plane.

Flight got canceled last minute and rescheduled 3 days later, as if we do not have jobs and children to return to. 5+ hours on hold with customer support with no answer. We booked a different airline and spent 3x as much to escape Montreal bc of Air Canada. Still haven’t heard from them. Boooo

Pros: The airplane was new and had in-flight entertainment (tablet behind seats) with new movies instead of watching on personal devices. Cons: the flight time was changed without informing us. When I booked the flight, the time was 13:30pm (also in the email confirmation). However, when I reached the airport, the time was conveniently changed to 14:55pm. When I asked at the counter, they said the flight always took off at this time. The booking was made by Air Canada, but the flight was operated by United.

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