A few improvements: 1. No signages at the airport that the porter airline was a codeshare and i could check-in at American counter. 2. Crew at the gate said they couldn't change my reward to Alaska - despite that being done previously 3. Despite there being many open seats, i was assigned a seat at the very back near lavatory, last row. Fortunately, the pilot wanted more people moved up so the flight attendants moved me up. It seemed very odd to have been stuck in last row with very few people nearby..

I didn’t receive any help when they messed up and wasn’t honest and the supervisor did absolutely nothing to help me so I had to buy another ticket at $537

There was No Flight. Both Kayak and Porter refused to honor my booking. I was asked for an additional 1,300 $ CAD to keep the flight. After several emails to both Kayak and Porter I was ignored. I had to cancel my March spring break plans, dog kennel and hotel. I had to re-book another vacation to Nassau in January w Expedia. I had to re-book a new vacation for spring break. Porter and Kayak both blamed each other and would not work together to fix this. Not cool.

Even tho the flight was a bit delayed the team was apologetic. Everyone was friendly and efficient.

The flight was a little delayed but check in was easy and boarding was quick. Luggage was quickly available and everything worked great.

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..

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!

Due to a known technical error that Porter has not fixed in over a year, I was unable to check in the children on my reservation online and had to do it at the airport. Upon check in, there were no seats together, which was an issue as we had young children. The gate agent did manage to seat us together by moving other passengers, which was appreciated, but the other passengers were never informed, leading to confusion and delay upon boarding. The flight was over an hour late; no explanation or apology was ever issued. The bags on Porter take a long time to arrive--over half an hour at Hamilton on my inbound flight, and not much better on my return to Edmonton.

Much roomer than air Canada! Great flight for the price. No complaints

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

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

My wallet was stolen while I was sleeping on the plane.

I checked a bag and there was only one agent to assist all customers with any issues.

Great setup on both flights except the last flight we got condensed dripping all over me in the last 20 mins of the flight

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Our biggest complaint about Air Canada is that if you don’t like your seat during check-in, there’s a fee to move elsewhere. On our flight from YUL to FFL, we were charged to change seats—just regular seats. What’s maddening is that the plane wasn’t even full; there were even a few people sleeping in the middle row sections (entire rows, completely empty), using them as beds. In my opinion, charging passengers for seat changes is a cash grab by Air Canada. They are definitely not the airline they were back in the day. I suppose they need to gouge the consumer now that they pay their attendants while on ground. One out of 10.

Allow me to book extra bag check in as free though I packed in 1 luggage but that was 7 LBS overweight so make another bag to free check in.

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

It was a smooth flight both in the sky and landing!

Fare was great, seat comfort the opposite as cushion was worn out. Ok for 2 hour flight, not for 4.5 hour flight..
