Crew were welcoming, accommodating and they worked hard to find places for all carry on.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

they made me check my carryon. There was space in the overhead bins.

Cramped and uncomfortable seats. Not enough room for 6’2” person such as myself.

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

Experience was good, the wifi hook up is somewhat tough

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

I selected "carry-on" for a round trip on Kayak, but my return flight on WestJet did not include a carry-on and they would not allow me to add one. My only option was to add a "checked bag" which I had to wait for on the luggage carousel after landing. Not a good experience.

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.

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Absolutely terrible, from the customer service to boarding the plane. On the phone, there was some mishaps with getting in my correct date and they did not help me retrieve a refund or any assistance. I’m gonna be reporting to all my followers and family around the region of Los Angeles to New York.

Not a tonne of food for purchase items for early morning.

Flight staff did fine once the plane actually left its departure location. But the 3-hr delay due to “flight crew was not present” followed by a 1-hr delay to “un-board ~10 people, and re-board these people due to an unclear security breach” was unacceptable.

Long delay die to pet mix up. Also bags took forever to get to carousel

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.

Could not understand what the attendant was saying during his announcements.

Once again our Air Canada flight was delayed! I'm hopeful competition arrives with other airlines soon and maybe they will make a better effort to be on time!

Boarding was OK. The overhead bins on the Havilland 400 are smaller than the allowable carry on bag sizes, making the bags to be jammed in and as a result slowing the boarding process.

Not so good. Got seat no 12 e. Squeezed between two people. No entertainment, hard to move around. Did not enjoyed that flight.

Flight delayed, Poor communication. Uncomfortable/cramped gate area. Insistence by AC staff that our carry-on bags had to be checked due to allegedly small size of overhead bins (not true, as we saw when we boarded). Awful-tasting snacks.

Flight was delayed again. The flight itself was very smooth, no turbulence or issues. No snacks were offered and no ice, only a plastic cup of soda (excluding the can). The attendants were very nice, but the amounts seemed stingy. The entertainment system wasn't set up properly to show our flight path (it said we were flying from xxx to ZZZ and the distance grew as we flew instead of shrinking) and so it kept timing out and going back to the home screen. The entertainment system worked very well. It's nice to have all the charging options as well.

It was a comfortable flight with very good staff on board. The in-seat entertainment system on the Airbus aircraft was easy to use and had an excellent selection of things to watch or do. The things that could be improved aren’t under Air Canada’s control — the gate assignment at Pearson changed twice for the flight necessitating a long walk from the originally assigned gates to the gate that the flight actually used. Not Air Canada’s fault… Pearson management needs to get its act together…

I have never been on an AC flight that left on time. Very little inflight service, at least in coach. For example, one beverage service in 5 hour flight (and they didn’t even offer water while we were waiting on the plane for over an hour to take off). You have to pay for everything, and wifi doesn’t work well unless you pay for the fastest speed.
