Liked Porter out of Pearson- New jets, complimentary beer and wine, 2 X 2 seating and pleasant employees. The only reason I chose to return this leg with Air Canada was the earlier arrival back into Pearson so I could drive the final 3 hrs home before midnight.

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

Take earphones to watch movies, we had the ones United airlines gave us on the way down so we were good.

I love the 2 seats per row. More room. The crew were excellent.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

Overall very good... staff were friendly and helpful. boarding was good for the most part, but a little hard to get our carry-on bags on there.... I think people should be directed to keep their coats and small bags with them until all the carry-ons are loaded, and then, if there is space, they can put their small bags and coats up top.. makes it much easier to put baggage up. i loved the internet feature, but the entertainment was not there unless you have your own Netflix or similar platform. My chair did not recline, which was very annoying, and the arms won't go up near the isle, which makes it tough to get in and out of the seat.

Staff were excellant. Only snacks served. Some turbulence so we were offered Free beer or wine.

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

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.

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Delta flight was on time, seats were comfortable, and crew was nice.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

They hired a new catering company the same day of my flight. They botched the job by not delivering the right carts and after THREE HOURS waiting, the flight crew timed out (flight was 19 hours long and FAA rules state crew can’t work more than 14 hours long). So they CANCELED OUR FLIGHT!! Worst experience ever. Avoid UAL at all costs.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

get E+, a must for 5 hours flight if you are tall

The first flight was better in terms of the aircraft.

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

The gate was too far away for the connecting flight

The flight was ahead of schedule. A half glass of juice and a cookie is pathetic! No entertainment possibilities. Not even a plug-in for phone or IPad if you wanted to watch a downloaded movie. Back to flying Air Canada!

The flight was ahead of schedule. A half glass of juice and a cookie is pathetic!

It was good, flight was on time, boarding was smooth and done in zones, food was good too but there was no form of entertainment. Luggage’s were intact. So an overall good flight

Plane changed to one with no entertainment system or ability to serve hot meals

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

No access to any entertainment No food other than a cookie or pretzels even tho flight was over the supper hour Seats very close together and very little leg room Staff was very good

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

Plane should have entertainment, instead of people paying to use wifi

The cancelation of my flight from Toronto to Edmonton without any solution given to me for my next flight. Very poor connection from Toronto to Edmonton

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

The layover was 6 PLUS hours and we were only given a $15.00 voucher. We missed our first activity in Quebec due to the delay.

Miserable staff as it was a late/delayed flight and crew wasn’t in the best spirits. Completely understood as neither was most of the passengers. Still unacceptable l.

It was a short flight, and no entertainment. That was not a problem for us, but there is no option for "not applicable". There was a bit of turbulence, so there was no food service.

the fact air Canada changed my flight from 850 PM to 815 AM with zero regard to the plans i made that last day, the cost i lost out on as things were non refundable amd shortening my first vacation in 7 years sickened me. when we purchase a service thats whats we expect. when we want to change the service we have to pay for that option but you do whatever you want . i called accessibility dept as i have a cpap and an implanted loop recorder first person said no problem just let security know you cant go thru scanners. then i got an email saying i had to fill out a fit to fly form . which again there was NO need to have that none. But that cost me money and time to have a doctor fill it out. then when i went to check in online i was declined i had to see a person at the airport instead. i couldnt get my boarding pass like everyone elseso here I was contacting air canada so I would have a easy travel experience and it ended up being a nightmare with more work for me, more cost and time. the flight itself was great the nightmare around it i will never subject myself to again. i tried to stick with supporting Canada but Air Canada was not worth supporting. very disappointed especially with a dept that is supposed to help disabled people not make an already challenging event not worth going thru at all.

Most courteous, helpful employees and all flights were on time.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

This flight didn't happen for me because of overbooking.

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.
