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

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Bumped from my connected flight, we arrived earlier than scheduled and I was bumped 4.5 hours later. There was no reason, they said my time I wouldn’t have connected in time. I had 41 minutes. None of Westjet customer service in airport could figure out why me and my 5 year old were bumped from flight we booked. We had 10 minutes to get to next gate after we got off the plane, one lady mentioned that’s not enough time to get to next gate. I was there in 3 minutes. Was originally suppose to fly out at 6:50 pm And was re scheduled to 11:45pm.

Everything went well, smooth flight, arrived on time, no lost luggage!

Horrible, delayed 3 hours due to a mechanical issue where the plane is deemed unsafe so we had to deplane after an hour on the tarmac. No credit was given even though plenty of passengers missed their connecting flights and then the baggage claim info showed that no flight was being loaded on the carousel whilst the bags were being dropped, so no one knew if it was the right flight or not since the arrivals screen didn’t show anything.

I think I'd sum up my experiences on this flight (Edinburgh to Toronto) by saying that Boeing 737s are simply too small for long-haul, transatlantic flights. The crew were excellent, the food was pretty good and the in-flight Wifi was a bonus. But 7+ hours on a narrow bodied aircraft with a single aisle and no in-built entertainment system, is a tough stretch - queues for the few toilets on board were lengthy at times; plus whilst the crew were doing food/drink service the aisle is blocked. It encourages you to stay in your seat the entire time (not great for those who need to get up and move around regularly) and the legroom is tight anyway. If this was priced as uber-budget, you could perhaps argue that you're getting what you paid for......but it wasn't and the price we paid was pretty standard for such trips (around £500 pp). I'd therefore urge caution and check the aircraft that is being used if booking with Westjet for flights to Canada from smaller regional airports on the Western edge of Europe. They do operate Boeing 787s from London and other major European centres - but it seems that if travelling from Scotland/Ireland the 737 is the aircraft of choice.......

Terrible. I was charged $75 for a checked bag when I only had a carry on. The lady at the desk said she couldn’t refund me the money and that I had to call westjet. I called the next day and they said they couldn’t refund me because there is no way to prove I didn’t have a checked bag.

I'm so frustrated my flight was canceled they give flight on August 5 which is not sure. Its was big mistake I booked my ticket from kayak.

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

To many flight at the same hour...no respect to handicap....

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

The flight was on time and crew were nice, seats were tight and there was entertainment available

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

The plane was broken so we had to change planes.

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

Iberia didn’t let me check in online or select my seats, the experience overall was not very pleasant

The flight departed more than an hour later than expected. The flight itself was good. No other problems.

It was pretty good. The transatlantic flights can be tough on any airline, but this was a decent experience. The only thing I disliked was the airline crew moved my carry on bag without telling me or explaining anything. If I was sleeping during that part, I would’ve assumed it was stolen.

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

I could not even make this flight due to Air Canada delay on my first flight. I had to be booked with American Airlines and arrived 13 1/2 hours late. Terrible customer service.

Bad, we had 3h delay without clear understanding, which lead to missing my connection flight.

Liked that it wasnt a full flight but we were asked to check carry on luggage as we were told the flight was full so i did, and that was not true. There was tons of empty overhead bins. No entertainment, and only one drinks and snack service when my ladt flight on aircanada in February, Montréal to Victoria had 2 drink service offers in the 5 and a half hour flight. Why only one this time? It felt very "budget" and cheap

Connection was easy to find and quick. Plane was older but comfortable. The food contained beans again so a similar problem of being in a tin can in the sky after eating beans. Overall flight was uneventful which is great.

Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

Flying with Air Canada is not pleasant at all. The plane is very old, meaning that there is no on board entertainment, the leg room is less, and it is dirty and in poor repair. To make matters worse, the crew was pleasant enough on my initial fight, but very rude on the return flight. Furthermore, the website advertises many amenities for international flights that are not honored when you were flying from the US to Canada even if your flight is five hours long. Even if you are willing to purchase food, they will likely not have over half of the advertised options available. In addition, you will pay twice the amount of a child’s order for an adult order of same item even though it is the same size as the children’s. It was just really bad on many levels I will try to avoid flying with Air Canada again at all costs

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!

Was charged for ticket, unable to check in online, made the line to speak to someone at the counter but was told I did not show up in the system as having a ticket to fly - even though I have the email with confirmation and credit card was charged. I could not purchase another ticket at the counter, only online which was not working. Ended up buying a flight on another airline at the airport. Called customer service to claim the cost of the original ticket, was told I showed up in their system as having a ticket but did not check-in or show up to board the flight. Currently pending review for refund via their customer service team, they were very nice and helpful over the phone despite the many glitches.

Do not book with this airline. Flights delayed over 3 hours and no explanation. They keep changing your itinerary every hour.

Awful. Not water, or chargers or space under the seats, the plane was very old and poor maintenance, seats really dirty, sticky, seats pockets with wires pinching your knees. Connection with no announcements, plane departed 1.30 hour earlier for an extra stop to refueling in Trinidad & Tobago. Even that we had a 3 hrs delay, seated in the plane in the runway.

Really bad. Uncommunicated stop in Trinidad & Tobago for refueling. Extra stop added 3 hours of discomfort without allowing off the seat. Not even water, or chargers or boarding groups.

Staff were unfriendly and rude. Was stuck on runway for 2 hours after arrival in Boston.

Horrible service. No communication from the crew as to why a 6 hour delay then cancellation

We waited in an overcrowded bus for over a half hour. It was uncomfortable. It would have been better to have waited in the terminal in a line

The food for sale on board has opportunity for improvement.

I paid extra for a comfortable seat in the second flight, but the plane didn't have those seats, the first one did

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.
