A very comfortable flight, an additional wash room could have made it almost perfect.

A very comfortable flight, an additional wash room could have made it almost perfect.

Look, I understand that Kayak doesn't know I cancelled my flight on Porter. So I didn't actually fly yesterday. My main disappointment is with Porter ticket fare policies, and maybe you can pass this on to them: At my employer's request, I had booked a full fare ticket with no change fees since my trip to Toronto would likely be extended. Indeed, when I went to change my flight home to a later date, I was told the Fare Difference would cost an additional $550. So much for no change fees lol! While I had the agent on the line, I hopped over to Kayak, searched for new flights on the date in question, and saw a one-way ticket that got me home for only $355. So I got reimbursed about $450for the unused half of my roundtrip and bought a new ticket for $355. What good is a full fare / no change fee ticket if they screw you with "fare difference" BS. I'm still flying home on Porter Airlines but they just lost a hundred bucks with their stupid shenanigans.

I flew with Porter yesterday and overall had a positive experience. The flight was delayed, but the airline did a good job keeping passengers informed with frequent updates throughout the process. My biggest challenge was actually in Terminal 3, where the speaker system wasn’t very clear. It was often difficult to hear the announcements, which made it harder to follow updates at the gate. On board, the experience improved significantly. The aircraft felt very new and well maintained, and the seats were surprisingly comfortable for a short-haul flight. One of the flight attendants seemed a little disengaged, but the other was excellent—friendly, professional, and a pleasure to interact with. Despite the delay, the comfortable aircraft, clear communication from Porter, and positive onboard service made for a good overall experience.

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.

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

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

Lavatories broke with an hour to go. At least we were on time.

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.

I'm so frustrated my flight was canceled they give flight on August 5 which is not sure. Its was big mistake I booked my ticket from kayak.

I loved the fact it was on time and it was a smooth flight to my destination.

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

Absolutely terrible, from the customer service to boarding the plane. On the phone, there was some mishaps with getting in my correct date and they did not help me retrieve a refund or any assistance. I’m gonna be reporting to all my followers and family around the region of Los Angeles to New York.

Nothing to like because my inbound flight was cancelled without notification by West Jet or third party, JustFly. I couldn’t take the inbound flight due to cancellation; therefore could not take the outbound flight back.

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

They are very proactive and made our boarding easy and always notified us about any changes well in advance.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

We paid $110 for more leg room. My traveling companion’s knees were right up against the seat in front. Where was more leg room. We feel ripped off. Food,,,there wasn’t any not even a bag of pretzels. As a result, there was very little service.

A 6 hour flt and only offered water twice the entire flight. A small bag of flavored pretzels was offered as well w/ the first round of beverages. The landing was ‘hot’ but I arrived safely. The plane was nice and new and the seats were roomie. I’m use to warmer more generous hospitality but all and all I’d fly with them again but I’d bring more water and snacks.
