A very comfortable flight, an additional wash room could have made it almost perfect.

A very comfortable flight, an additional wash room could have made it almost perfect.

Look, I understand that Kayak doesn't know I cancelled my flight on Porter. So I didn't actually fly yesterday. My main disappointment is with Porter ticket fare policies, and maybe you can pass this on to them: At my employer's request, I had booked a full fare ticket with no change fees since my trip to Toronto would likely be extended. Indeed, when I went to change my flight home to a later date, I was told the Fare Difference would cost an additional $550. So much for no change fees lol! While I had the agent on the line, I hopped over to Kayak, searched for new flights on the date in question, and saw a one-way ticket that got me home for only $355. So I got reimbursed about $450for the unused half of my roundtrip and bought a new ticket for $355. What good is a full fare / no change fee ticket if they screw you with "fare difference" BS. I'm still flying home on Porter Airlines but they just lost a hundred bucks with their stupid shenanigans.

I flew with Porter yesterday and overall had a positive experience. The flight was delayed, but the airline did a good job keeping passengers informed with frequent updates throughout the process. My biggest challenge was actually in Terminal 3, where the speaker system wasn’t very clear. It was often difficult to hear the announcements, which made it harder to follow updates at the gate. On board, the experience improved significantly. The aircraft felt very new and well maintained, and the seats were surprisingly comfortable for a short-haul flight. One of the flight attendants seemed a little disengaged, but the other was excellent—friendly, professional, and a pleasure to interact with. Despite the delay, the comfortable aircraft, clear communication from Porter, and positive onboard service made for a good overall experience.

The Flight took off 2hrs late because there was no pilot showing up when the flight was ready to board.. Though the cabin crew was present and had prepared the plane, the FO turned around after 15 min and went away. A crew to fly the plane finally arrived over an hour later and we were able to board 1h30 min later than planned time... until everything was loaded, we left 2h late from the gate. This was a small plane, so don't expect any Entertainment... Wi-Fi access on board would work, but took an awful amount of time to figure out and get it work (I'm an IT person). Flying as VIPorter customer, I was expecting at least some warm meal, but everything served was just cold.. except the coffee maybe. Even in so-called VIPorter seats, space is cramped and trays are so tiny, you can barely setup your food. Flight caught up during the coast-to-coast crossing and was able to recoup about 45 min from the delay.. still arrived very late in Vancouver and had to wait a long time to get our registered bags. Let's see how the return flight will be in a few days..

It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

Organization and the adjusted times but the snacks could be of a bigger portion

Our flight was delayed by a bit. I appreciated that we were kept informed on why periodically. Boarding was fine. I overheard one flight attendant sounding very rude to a passenger who was not paying attention to the safety demonstration. The snacks were minimal as it was a short flight. There was no entertainment. Overall the flight was good back to LGA.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

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.

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 .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

Flight got canceled last minute and rescheduled 3 days later, as if we do not have jobs and children to return to. 5+ hours on hold with customer support with no answer. We booked a different airline and spent 3x as much to escape Montreal bc of Air Canada. Still haven’t heard from them. Boooo

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

One of the flight attendants was very attentive to a couple traveling with a child under 1 one year old.

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

I’m 5’3 115 lbs and felt so cramped in this express jet. My carry on actually meets the requirements and still had to be stuffed Into the overhead and barely fit down the aisle. Not a great experience. Air Canada needs to replace these planes.

My wheelchair was sent somewhere else, it wasn’t at my ending destination.

The plane used on this flight didn't have a working air conditioner. It was extraordinarily hot and uncomfortable.

Slight delay with arriving flight but explained and still made our destination on time

Both flights were delayed in taking off. The flight to Montreal was delayed by several hours. We also sat on the runway for quite a while for both flights.
