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!

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.

Other than wifi no on board entertainment. Will use them again, roomier seats than other airlines and snacks and beverages, better than average

I like it, but the food isn't good. They need to offer more simple things. This bowls that have so many things your don't know what your are eating. The milenials like it, no the rest. And last but not least, they allowed somebody have a huge dog, vey agressive and fidgety in the flight. That's horrible. No animals should be allowed inside the airplane, what about allergies, etc

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

The flight was half empty yet they charged me $50 for a basic carry on! I saw how passengers of different colors were treated differently.

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.

It was very good but no tv but the experience was great

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Nice complete meal included and great services. Plus the plane was very clean.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

The flight was cancelled less than 24 hours before departure. The alternate flight was a day later going from Grenada to Toronto to Vancouver to Calgary to Montreal. 2 days in the air. Not serious, Very bad service

I like the wider seats, Plus lots of legroom, Lacking entertainment, no tv or screen to play with

Liked in-flight wifi Did not like - nothing to complain, really. All good

I like the web site, prompt notifications, website checks in process, and airport check in. The flight attendants are attentive and polite. The return flight was 2 hours late and reason vine doesn't sound like an unplanned and unexpected issue (scheduled plane maintenance).

The keg from Edmonton to Toronto My wife found it very cold. Other than that great flight.

Smooth flight Staff were courteous and welcoming upon entering and exiting the plane Pilot and crew provided frequent updates Leg space was not pleasant but manageable

Everything was good except I was a bit disappointed that I had to pay US $150 for bags.

Flight itself good .Landing at terminal3 and connections to terminal1,it is connections nightmare,specially for disable person

The seats very Uncomfortable, no meal and no entertainment for a 4Hours flight. Smooth Flight, Great Take off and landing. Superb crew!

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

It was just fine. I managed to make all my connection too sbut had trouble in Munich with no wheel chair and trouble trying to get help from the airport people to get to the other terminal for my flight. Finally a wonderful lady Amelia, helped me to make my flight connection Timon with zero time to spare.

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

Elderly female flight attendant was not customer friendly. There were only about 12 people on a regional jet that had about 60 seats. There were 8 exit row seats and none of them were taken. We attempted to sit in those seats and the flight attendant gave the standard " you didn't pay for those" so she would not allow us to move. What harm would that have caused ? They assigned seats to 5 of the 12 people in 2 rows, row 20 and 21. A simple friendly customer experience gesture of allowing us to sit in exit rows would have gone a long way in me having a very favorable impression on Air Canada. After that I have very poor impression of Air Canada and will not fly with them when I can avoid it.
