If you can avoid checking yoir bags do so the YYZ bagge collection is brutally slow(30-45mins wait)

All gulf and far eastern flight have good boarding and dining facilities.
ElizabethFlew with Air CanadaSFO-YYZMay 2024
When delayed happened I would suggest for the crew to let passengers board in and just wait for the one crew missing to arrive and joined the crew as soon as crew member arrives other than passengers waiting this helps time consuming . And passenger not rushing for connecting flight.
HazelFlew with Air CanadaLAX-YYZApr 2024
Be appreciative of the crew, be patient generally and follow the rules
Verified travelerFlew with Porter AirlinesSFO-YYZMar 2024
Be on time, don’t carry so much cumbersome baggage on board.

Rouge seats are terrible for comfort. Might make sense to fly via Denver
Verified travelerFlew with United AirlinesLAX-YYZJan 2024
Take earphones to watch movies, we had the ones United airlines gave us on the way down so we were good.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We were given a complimentary seat upgrade which was so unexpected but so lovely!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Only packaged snacks were served. It was a flight at lunchtime and a hot meal would have been a great.

Reserve check-in was very slow compared to regular check-in. Internet was slow

Lavatories broke with an hour to go. At least we were on time.

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

Flight was delayed. Arrived in Vancouver at 3 am. Not a great experience.

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

Dogs. Dogs. Dogs ! Who the hell thought letting dogs on board was a good idea ? Yapping dogs on both flights ! They ruin the experience for everyone else around because you try to accommodate everyone. Please send me a refund.

We booked Premiere (their version of first class) and Premium Economy seats. We boarded an old swoop flight with all coach seating. No benefit to paying higher fare and no apology or reimbursement.

Flight was delayed 1.5 hours. Baggage took 45 minutes to reach carousel

The quality of service at WestJet has really decline in the past couple years. Now they rarely leave on time and are full of excuses to obviously try to minimize their responsibility for compensation. Reality and what is mentioned at the gate for delaus rarely jive. If you apply for compensation even if appropriate, you are declined. They need to get back to doing the small things great rather than look for more reasons to grab money.

Credit to the check-in staff for offering no-charge to check our carryon. We had 2 checked suitcases already, and it was easier instead of at the gate.

Your staff on the flight back to Calgary were very friendly and efficient .

Everything was good till we got to yyz...then we got to the gate and there was NO GATE AGENT. We waited 15 min before disembarking. No internet No IFE Old aircraft Second leg in two weeks NOT IMPRESSED

The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

I was not even asked if I want some water. Joke. Steward gave me a biscuit cover in chocolate and did not even look at me.

Ok Did not like that the second leg of flight was moved earlier making it a rush to make

Overall it was great! Seats were comfortable. We were offered snack and drink on the way to Florida but only a drink coming back. Free messaging for aero plan members was a great feature to have on board so we can connect with loved ones … entertainment like movies and shows was also a good selection!

The problem in part was with the airports, not really the fault of Air Canada. Confusing directions regarding the gate, in Seattle the recommended shuttle train entrance was not working. Simular problems in Toronto. Baggage arrived in good time. Marx Bros movie on entertainment from Seattle. I was told I was laughing too loudly, by the flight attendant. No lounge in Seattle. Lounge in Toronto excellent.

Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.

I arrived for my flight and was told I was now on standby as my assigned seat when I purchased my ticket was just deemed unusable 15 mins ago. My parents had to wait and hour and a half at the airport to see if I’d get in the plane. Finally when all passengers had boarded the plane I was finally told they did have another seat for me. When I boarded I saw someone else sitting in my originally assigned seat. It was in the emergency exit row and has extra leg room. I have sat in this row many times and am able to help in an emergency so no reason for me to have been kicked out of this seat. The new seat I was assigned had no padding and was extremely uncomfortable. Upon landing my back was very sore and I will probably need to see a massage therapist to help ease the tension. There was no tv or way to charge my phone on the plane. Worst flight I’ve taken in a while by far.

My wife was in a wheelchair. Most accommodating and kind staff!

The flight was delayed 2 times. The 2nd time with no knowledge of why.
