The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Boarding was a little chaotic but it was a very large flight. It just wasn’t fast. And there was no noticeable difference between zones boarding.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

I think as another discount flyer they stepped up the bar. I think they should stay around for awhile

L’embarquement et l’arrivée ont été laborieux! À MBJ à la barrière d’embarquement, c’était sale et mal ventilé. A l’arrivée à YUL, il n’y avait pas d’équipe au sol pour recevoir le vol! Et je déplore que Transat n’avait pas de personnel de bord qui parle le français 🙁

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

Boarding, staff and flight great. A bit disappointed with no in flight online entertainment but I'll live. Landing was a bit of a jolt (more than usual) but hey everything else was smooth. LoL

I’ve been delayed for two days and I’m still stuck in Honolulu tired spending money

1.5 hours late departing YVR for a 14-minute flight. Packed waiting area. Full plane. Families with tired, screaming kids. 40-minute wait for baggage at YYJ. For a Dash-8. Obviously there was some kind of breakdown but there was no communication from anyone. Most of this was not WestJet's fault but it was an unpleasant night overall. I fell asleep in a chair waiting for the luggage carousel to start.

Nothing to like about flying in the Dash 8s. With very small seats, little legroom, and a very noisy plane, nothing about such trips is enjoyable.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Difficult to say. Over crowded but that is the fault of the airplane not WestJet

For some reason there was a change in the cockpit which delayed us by an hour

flight changed by airline. then could not check imto mew flight because kiwi had messed up the reservation. still waiting to depart…

Crew was rude.didn’t even say hi or welcome to board

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

The flight I was connecting with waited for me even though my 1st flight was late. I really appreciated that.

The seat is too hard and my back and bottom are having servers pain

There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.

Great crew, friendly. Found the trip long just sitting with no onboard entertainment

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

Flight was delayed, I tried to leave 2days earlier was told to report to airport for standby only to be turned away after paying for an Uber both way from Little Elm TX.

They need to organize a better system for boarding and esp unboarding. Idiots rows back cutting everyone waiting to get off first. No. Wait your turn

Terrible!!!!! Gate changes are a nightmare for elderly. I had to walk to another Terminal without any assistance! It was awful. When I finally arrived in Philadelphia my back and knee were killing me.

It was only a 50-minute flight from CLT to SAV. I could not get wifi in CRJ 900 plane,

I had first class itinerary, yet they put me boarding group 5 from FNT to ORD! I spoke with the gate agent though, and she let me board in Group 1 like I should have been assigned. Would've liked water on that flight. I'm glad that I asked about food on the flight from ORD to DALLAS. If I fly United from ORD to any city in Texas, they always offer a hot meal and regardless if it is a time in between meal times. The excuse was that it was not dinner time yet. It was almost 6pm?? And the flight was over 2 hours. There were some healthy snack options at least, but fresh snacks like apples or something would be nice. At least offer cheese plates or similar. Please bring seatback screens like United is doing. The flight attendant in first class was wonderful.

While going to Porto Portugal my luggage was delayed for 3 days . While coming back My flight was delayed and missed my connecting flight . No compensation for delayed luggage. Not a happy experience .

less delays; there was an hour+ delay on both flights. self serve check in kiosks weren't available for British Airways flights

Luggage got lost, need more staff not sure why we checked in over 1.5 hours before flight boarding .

It was an enjoyable flight. I guess the airlines will never go back to catering, they save so much money.

Lovely staff for a short flight! Complimentary wine too made me happy.

5 delays to departure. Finally left 2 hours after scheduled time. Further issues with “paperwork” when we were ready to push away from the gate. Air Canada has a real problem with flights between Montreal and Toronto over the last 24 months. Of my 12 flights, 8 have been delayed or cancelled. With no compensation. I now drive between Toronto and Montreal whenever I can. At least I know I will get there when I planned to.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

Terrible crew. Mediocre food. Terrible headphones. No Bluetooth connection for entertainment. Crying babies. Horrible experience.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Difficile quand le gate change, les deux fois. Quand on m'a changé les sièges que j' ai réservé, les deux fois. On m'a dit que j'allais être remboursé et rien eu encore

Air Canada continues to disappoint in almost every way. Probably the result of a monopoly, so NO need to improve anything

My flight has been canceled and I had to cancel entire trip.

Nothing to say: I always have a good time with Air Canada
