It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

Free Wi-Fi is good. That’s all - food mediocre, unfriendly crew, poor communication after trying to file a claim for my lost bag, which Delta didn’t even know was lost until I told them.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

Flight did not have seat back entertainment and the wifi was iffy.

The seats are uncomfortable, feels like a small seat pad on plywood.

Wifi did not work and they only served water, coffee, or tea.

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

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.

My suitcase was completed destroyed. The top part is broken and unusable now.

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.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Great overall. Quick boarding, attentive staff - great experience in premium class.

1. Nowhere to sit at the gate D4 2. No control of lining up in different zones 3. People pushing in during the line up of zones. 4. Certainly not in a dignified manner.

Air Canada was great! From the airport at Montreal to boarding to the food on board the plane. The crew was great too! There was a slight issue with some other peoples’ tickets that I overheard about but the crew handled with care immediately to ensure everyone was comfortable and we could takeoff! Great experience with Air Canada

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Boarding could be improved, no need to wait after a previous group is completed

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

Very good ! I would recommande it to my friend and family

the service was fine but would have which that the audio for announcement is better.

My first flight left so late we knew I would miss my connection. Rather than redirecting me then, they made me take a flight to Montreal, then Toronto (there was a flight leaving for Toronto when I was in NYC, no need for me to also go to montreal). Then they gave me a food voucher that did not work (4 places would not accept it). At least they gave me a hotel automatically, even though it was a cheap crappy one. I'm still not home, and it's been over 24 hours. I'm exhausted.

The boarding was at a dual gate hallway and there was only one spoken explanation about which way to turn to board the correct plane. It wasn't marked visually at the split in the gate. The phone charger did not work at my seat. The temperature was quite chilly throughout the flight and the recorded announcements were extremely loud for a small plane.
