The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

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The plane used to go to Chicago was a bit outdated and needed a refresh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

The flights were on time and I appreciated that the cabin crew helped passengers with overhead luggage - finding space etc - despite not being paid. Apparently their wages don’t start until takeoff. This makes no sense whatsoever.

It is stupid to have to go to Atlanta in order to get to Rochester NY. I was up for 36 hours because who can sleep on an airplane. I'll next do tht again.

Always a pleasure to fly with WestJet. I am however frustrated about the rising costs. We have started to resort to Ultra Basic fares to afford but really missing the extra bag but too costly.

The crew were all helpful, kind, and effective. There could have been more space under the seats.

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!

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.

It was a good flight and we arrived on time, plane was clean.

The flight was fine. Long wait at security and for wheelchair. Got to gate about 5 minutes before boarding

Disappointing flight experience! ✈️ A two-hour delay, insufficient food and drinks, terrible cabin crew, and poor service overall. No toothbrushes or toothpaste provided for a long-haul flight — absolutely unacceptable! Compared with Japan Airlines, the difference in service quality is unbelievable. Overall, this experience was simply not good enough.

It was our first time flying wit Air Canada. I found most everything very good, however, our flights leaving and returning were both delayed. And we were met with no place to de-board the plane and had to wait an additional 45 minutes on the plane after arrival. That was very disappointing. Also hefty fees both ways on what would normally be a carry on bag on any other airline.

Traveling from Montreal to SFO, after landing in SFO, there was no announcement about where to claim our luggages. Our gate was in Terminal 1, and went to the luggage claim area in T1, but couldn't find any information on the screen. Eventually, an airport agent told us that our luggages would arrive in Terminal 2 luggage claim area.

Very good, easy to check in, 24 hours to cancel, good prices, nice flight attendants!

Great flights. Only criticism is when landed I. Montreal, wheelchair service has no signage or anyone letting you know where to go , just an older gentleman at the desk looking confused

This is a regional jet. As far as those go it was average. Again poor quality for an expensive seat. Not worth the upgrade

All went really well. Except that I was randomly chosen to be thoroughly checked!!

We were reluctant to travel with Air Canada after reading many bad reviews; however, we were more than satisfied with the experience flying from San Francisco to Montreal and back. Seats were comfortable (although on the return flight we had very little leg room) and the crew was friendly and competent. The entertainment was outstanding, with hundreds of choices, from movies to shows to comedy. Our luggage was delivered in a timely manner (a little slow in San Francisco) and we were sent tracking notices all along the way through the Air Canada app. I wouldn't hesitate to travel with Air Canada again.

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

Delayed fly, employees at the counter not professional and lack empathy to help, crew inside the plane very rude and unfriendly my fly was delayed for 2 hours. For being this the first time I will say if there is not other option then I will fly with this airline. One more thing, the pilot never said a wakes the whole fly but until we are about to descend. Not a welcome message the wether at the destination and time to arrival. It seems that the airplane was flying by itself without pilots. Terrible.

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.

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.
