Airline reviews

The staff was amazing. Best service I’ve had on an aircraft in a long time. Was not particularly happy with the food. Flight was at 10:50 and left home too early for breakfast and wasn’t able to purchase food at airport and felt for sure I could get some breakfast to buy on airplane. Nope as food was served around 11:30 and only one choice left (I was at 22C) so ordered the chicken dish thinking I’m getting a hot meal but cold chicken with rice and carrots etc. I was looking forward to a croissant sandwich and a hot cup of tea. The FA was kind to explain they were serving dinner at that time. She was lovely Other than the disappointment with the food the staff was amazing. On my return flight I will make sure to eat and take some food with me so I’m not hungry or disappointed. This was my second time ever flying Porter and will consider checking them when I next come to visit my daughter. Have to say it again best crew I’ve ever experienced on a flight and I travel quite a bit. Thanks.

I didn’t receive any help when they messed up and wasn’t honest and the supervisor did absolutely nothing to help me so I had to buy another ticket at $537

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.

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

Arm rests are too small and too close. No screens, movie selection was very limited and poor. Food is pretty much overpriced cheap convenience store food.

I didn't have any problems during my flight. My main issue is with airlines in general, they keep offering less and less every year, AirTransat is no different.

Crew was good, helpful. Flight ran on time.would have liked to take airtransat home to MTL. But the price back from San Jose Costa Rica was MUCH more expensive than the flight from MTL to San Jose c.r.

i was not able to take my flight because the information i needed to book my dog correctly was not provided

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.

I was very nice to arrive earlier than scheduled. Very much appreciated. No issues with flight. All was good.

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.

Aer Lingus App never showed the gate and the board did not update until very close to the time the gate was due to close. Both planes departed late but no announcement was made which would have saved a run for the gate.

Flight delayed 45 minutes almost caused us to miss connection to transatlantic flight.

Vegetarian food options were pretty tasteless. Gob of rice with absolutely no protein, barely any vegetables, and poorly seasoned. Food was the major disappointment of an otherwise good flight experience. However, food is a differentiator on long haul flights.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.

Caring & friendly crew. Most important: got us SAFELY to our destination!

Friendly flight attendants, decent food if you can eat dairy.

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

Access to movies was rather confusing. Apart from that, I have no complaints.

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Flight left on time. The crew was very friendly. I had to buy a proper meal. Small cookie and a drink just doesn’t cut it for a 4.5 hours flight.

Experience was good, the wifi hook up is somewhat tough

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

My luggage was damaged 1 wheel was out I can't find it nowhere

Took 3 hours to check in and drop off our suitcases. Half of the passengers were still in line by boarding time. The computer systems and staff were very slow. Staff were also disorganized and kept allowing later flights to skip lines. Suitcases were piling on that several other passengers didn't get their suitcases. Then, we were sitting in the plane for 2 hours and were told that the flight was overbooked. We missed our connecting flight and had to fly the following day but with a stop over. Good thing ONE WestJet customer rep was pleasant and actually knew how to do her job when we wanted to rebook to a direct flight. Thank you to Kim at Toronto airport. Terrible experience at PUJ. Won't go back to Dominican Republic.

Great seats, super comfortable, but no in flight entertainment which was a let down

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

Excellent flight crew. Very comfortable plane. Entertainment options on air Canada were great!

Flight was oversold. Seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

Boarding is always chaotic. Delay was over 2 hours while inside plane . Crew not very friendly

Congested seating area Toronto Poor announcements Terrible food in flight Limited entertainment options

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

Comfortable seats with good leg room. But not screens on seat backs.

I was rescheduled when I missed my flight due to border clearance issue

Flight was delayed twice which made our arrival extremely late (actually into next day). Not an easy travel. But when we requested assistance for boarding we were really impressed with how they helped us! Strongly praise their assistance.

It was out first time flying Air Canada and it was ok, comfort-wise. I hope airlines are able to get a quiet room installed for young children flying. Screaming and crying the whole time in business class is quite unfortunate. That was the only thing that really messed up the experience.
