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

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.👍

We are a senior couple (70+) and chose emergency exit seats so we would have 2 seats together and neither of us had to sit in a middle seat. My husband is type 1 diabetic on an insulin pump and I monitor his blood sugar levels. I am 5'9" and 250 lbs and found the seats extremely uncomfortable. Toward the end of the flight I developed diarrhea which lasted a full 24 hours.

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

We were treated well by the staff at the airport and on board aircraft. Delay was uncontrollable due to the weather. Had to wait for another gate as we were late landing in Fort Lauderdale.

I was supose to have a carrey on incluided for each passenger and they made me paid 75$ each at the gate.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

I did not like I have been charged for my carry on

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Very good. A lot better experience then I expected for an economy flight.
