Airline reviews

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.

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.

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

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

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

Smaller plane. Food and bar service for free is amazing. Drinks were in glass not plastic cups.

Poor landing as we overshot the runway and had to re land the plane. Lost both of my luggage not found as of yet. Had to pay extra money for my luggage in USD, now great my luggage is gone. Will not fly with Porter again.

This flight to St. Johns was really good. Boarding was a breeze. We left spot on time. Seats were actually pretty good. Recliner further than I expected. Three more flights to go we will see if this is the status quo for Porter.👍

I was not happy with AirfareAssist, the agency that kayak advised me would be handling my booking. I was advised by porter airlines that I had been overcharged for the Basic express , a option that I had asked airfare assist to help arrange after I realized that the basic fare I had chosen with porter did not include a carryon. At each checkin porter advised I had been overcharged for this . They advised that money would be refunded to my credit card, however, this is not likely to happen as it is not my name and credit card that appeared on the porter invoice, but that of another individual/agent. When airfare assist was arranging the basic express with porter on my behalf, they asked me to confirm that I agreed to pay $263 USD for this. I did agree, as I was advised this was needed to proceed. When I checked the invoice on the porter website and saw that it was not my name and credit card on the invoice, I was advised that this was how airfareassist processed the payment. The Porter invoice indicated a billed amount of $126USD I will not use Kayak or their designated AirfareAssist again
