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.

Maybe glass of wine would be nice at no charge

We traveled with a 7 year old that has autism and he is significantly cognitively delayed. Your site makes it known there are no wagons allowed even if they fold down flat and many autistic children cannot travel without one because they are unable to follow directions or cooperate with walking through the airport and are too big for a stroller. Please consider making exceptions for our special needs children. Also it would be very thoughtful if you’d allow seat selection for no fee for special needs families. The autistic child we traveled with must sit behind another adult in our family because he continuously kicks the seat in front of him and is unable to understand why that is disruptive. We had to pay quite a bit extra to have our 4 seats situated with 2 in row 19 and 2 in row 20 directly behind.

It would have been nice to know there was no on flight entertainment

Our itinerary included a 1 hour and 30 minute layover, which should have been sufficient under normal circumstances. However, our original flight was delayed. Before we even deplaned, we were instructed to collect our checked bags from baggage claim, clear immigration and customs, and then recheck our bags for the connecting flight. The airline knew—or should have known—that this was impossible. Checked baggage acceptance closes one hour before departure, meaning there was no realistic way for passengers from the delayed flight to recheck their bags in time. Despite this, the airline gave us misleading instructions instead of informing us that we would likely miss our connection. We completed immigration and customs in approximately 10 minutes, but our checked bags did not arrive at the carousel for more than 30 minutes. After collecting them, we had another 10-minute walk to the baggage drop area, only to find that no airline attendant was present. We then went to another airline counter, where an employee told us this had happened before and that there was nothing they could do because the baggage acceptance window had already closed. At that point, there were still 40 minutes remaining before our flight's departure, yet no one was willing to assist or offer a practical solution. When we asked to be rebooked, we were simply told to call the airline's 800 number ourselves. There was no accountability or customer support at the airport, leaving us stranded in a foreign country with no immediate assistance. After finally reaching an agent on the 800 number, we were rebooked on a flight for the following day. However, we were initially told that the airline would not provide any hotel accommodation and that we would have to arrange and pay for it ourselves. Only after making multiple calls and speaking with several different agents did one representative finally issue a hotel voucher. The entire experience was an exhausting and frustrating ordeal. What should have been a 20-hour journey ultimately became more than 30 hours due to the airline's poor planning, misleading instructions, lack of accountability, and inadequate customer service. The unnecessary delays, confusion, and absence of meaningful assistance caused significant physical exhaustion and severe mental stress. This experience fell far below the level of service passengers should reasonably expect.

Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Good flight. We were all boarded in good time for departure time but baggage loading had barely begun. So left late. No food just snacks and basic drinks for free (food also for purchase). No entertainment as again, unable to connect with wifi on WestJet despite being a rewards member.

Average flight, comfort was as expected for a 10 hour flight. The service was fine.

Everyone was extremely friendly and nice, from the front desk to the cabin crew!

My luggage was damaged 1 wheel was out I can't find it nowhere

This may have been the hottest cabin temperatures I have experienced on any flight prior to take off lasting for approximately 30 minutes. I am not typically one to complain but I was genuinely worried about the health of several passengers on the flight due to the extreme temperatures including a small toddler.

I got bumped by Qantas to American Airlines incurring a 6 hr layover at lax. I was not happy

Air conditioning was out for about 15 minutes that made it uncomfortable. WiFi went out halfway into the flight. Flight was about 45 minutes late.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

Baggage allowances are terrible and the experience of only being allowed one bag and paying so much to take sporting equipment to a known ski area should be addressed.

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

Good service, friendly staff. Food was average for airlines and the seats were small.

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.

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

My flight was delayed My connection was almost missed. My bag was lost My valuable items get damaged

It was great! Very comfortable plane, crew was great, would definitely take this flight again.

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

Awful, I was bumped from my buisness class seat because the airline decided to forfeit my seat to a pilot and stick me in the very back of the plane. My flight was delayed by an hour, boarding took an extra 30 minutes longer then it should have, and the in flight entertainment system was broken for my entire flight. I have yet to hear from Air Canada with regards to a refund for my ticket so in total I'm down about $1400 dollars for my tickets. Moving forward if I can avoid using Air Canada in the future I will be doing so even if it costs me extra money.

Flight was late missed our connection to Indianapolis no hotel rooms really difficult finding a room hope to be in Indianapolis one day late and multiple flights to even get there.

Kept me waiting for hours with the excuse of aircraft needed to cool down and then cancelled.

Everything was great except that I wasn’t issued a boarding pass for the second flight so they would not let me into customs until I had said boarding pass. Luckily a gate attendant from another Air Canada flight was able to print one for me so I could go through.

First time flier on Air Canada and absolutely loved it. Everything was so clean. Friendly staff. Easy boarding.

Flight attendants had an attitude with everyone, not sure they should be working with customer service if they cannot show a pleasant attitude. Underwhelming, to say the least. The food was awful, and nothing could be purchased from Toronto to Tokyo. Do better, Air Canada.

I suppose to board the plane AC5110 to San Francisco on July 16 2026 @07:00 am and arrive San Francisco at 09:25 am. At 9:30am still in YVR I was told the plane was delayed until 11:30 am to take off. Not until 11:35am the pilot of the plane declared that due to hydraulic system problem this plane was cancelled. After waited in a long pile up for negotiating with the counter-staff, I finally got the tickets for myself and my wife Yim Mei KONG firstly to Seattle and then transferred to San Francisco on the plane AS 2014 & AS 791 with Alaska Airlines. I suppose to attend the funeral of our friend in San Francisco on July 18 and a Memorial Gathering for the Birthday of the deceased on July 16, 2026. I arrived San Francisco at 9:40 pm that day (12 hours later) and couldn't joint the Memorial Gathering. This upset me a lot. I am seeking for compensation of this failing trip. Please let me know how to and where to forward my complaint.
