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.

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

Westjet has a terrible boarding crew. I had a zone 3 pass and my wife and kids had zone 9 as we purchased tickets separately. After scanning our boarding passes, the boarding Filipino lady rudely says that my family has zone 9 passes. I said I have 3 and wanted to board as a family and she started a rant that they have 9 and they were small kids to board with me. I told her that I am not going to separate family because of this and what she said didn’t make sense. It’s a shame to Westjet if they have such policy. It’s a shame to the WestJet employee to start this rant after the passes were scanned. Westjet has to train people to speak politely and not with rude demanding tone. If that’s Westjet policy, I will pick a different airline next time. Westjet is not the only one out there.

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.

Calgary WJET supervisor was the most professional, and diligent official who I have experienced personally to resolve our flight issues.

Never got to take the flight due to app kinds of problems with the earlier WestJet legs of the trip.

Sat on the tarmac for 1.5 hours after landing. The flight was OK, after that, not so much

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

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Wheelchair help is not reliable & chaotic. No food and minimal liquids for a flight at 6;25.

I don’t think the on-board testing worked on any of the 4 Air Canada flights for this trip. And in this particular flight, the entertainment and WiFi was out for a portion of the journey.

Everything was going well until we disembarked in Dallas. A bit of a wait getting acess to disembark from the plane. But the worst was getting luggage from the baggage claim area. All passengers waited over one hour before bags began to make way to claim area. To make matters worse no airline staff informed us of what the delay was. Many tried to call the air line customer service number to no avail. It was late at night with most the airport shut down. Bad way to end a trip.

The only problem I encountered was they changed the gate on me while I was sitting down but no one notified me, they had sent me an email and by coincidence I checked it and found out that they had changed my boarding terminal. No one notified me and when I had asked the lady she told me yes this is the spot while they had already changed to another gate/terminal

Easy boarding and very practical. The WiFi and outdated entertainment system could have been better.

I will always try to avoid Montreal Airport in the future.
