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

As a first time flyer with Porter I was happy with the service and comfort of the airline.

3.5 hr delay for a 1 hr work flight. No information as to why the delay until 20 mins before boarding.
