Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Boarding was a little chaotic but it was a very large flight. It just wasn’t fast. And there was no noticeable difference between zones boarding.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

We could not check in early, I think because we purchases through a third party, therefore once we got to the airport, no seats together, and only middle seats. Will never do that again

Airport monitors did not give the gate for our flight returning Detroit to Vancouver Juice served from glass storage containers are a far more healthy alternative for people. And would also minimize the need for recycling plastic or aluminum containers

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

I had planned to watch the Westjet entertainment for the entire flight however, because the seat mounted outlets in our row did not work.

Not a bad flight but our priority tagged luggage was the very last to come down the carousel.

Plane had a flat tire, delayed boarding and takeoff but one in the air, smooth. Make sure you have downloaded the WJ app before you leave. When on board, you can watch movies or TV shows offered on the app, it passed the time very quickly.

Our recent flight from edmontown to kahalui was excellent. The service staff was very friendly, knowledgeable, funny and attentive. Thanks to all involved that made or travel such a pleasant experience and we hope to fly with west jet again soon

The flight was delayed and I missed boarding my 7 day cruise. I had to book a separate flight home

No real issues just wasnt able to hear / understand any announcements flight attendant was making but everything else was really good- ended up checking my carry on case for free which made deboarding quicker. I would fly West Jet for all my flights.

Seats were comfortable and leg room was good. Slight delay for boarding but nothing too bad. Would fly with them again.

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

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?

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10 Tips for people flying porter from Boston. The airline doesn’t have inflight entertainment No TV No WIFI. Bring your entertainment with you.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10

Wasn’t on the flight- again. Bad weather in Halifax and I was in an accident. What a poor experience to have to pay for all this flight and not be on it

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

My flight has been canceled and I had to cancel entire trip.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

There was no food on this flight. We had less than 1/3 full plane and were not allowed to spread out. Staff gave the story of the plane had to have all of us up front for 'balance.' Total bs.

There were changes to my flight with many email and very difficult to keep up with details of changes. I consulted Air Canada website that said I was to depart Casablanca at 9:35 but when I got to airport that take off time was delayed by 2 hours. That's 2 hours at an airport instead of bed. I don't understand why Air Canada website didn't show the change in take off like they showed the change in transfer. Do better.

I was delayed from Montreal to Tokyo for 3 hours and they didn't compensate anything

Flying Business on Air Canada is wonderful. With ultimate destination in US, you get the Lounge. Only problem is there was no lounge in YQB so it had to wait until connector in YUL. Flight itself is only about 30 min like the old DC-NYC shuttle so there was no service other than almonds and the bottle of water that was at your seat upon boarding. Would have been nice to be offered a beverage and there was enough time to do a quick pass for the 16 seats. That and having a lounge in YQB are only complaints, but that's very first world complaint. The FA were cordial and professional if not warm. It was a good flight and I'd do it again. But, word to the wise, it's a very different experience doing border check in YUL than YYZ. Long walk and had to go through full screening (including taking off shoes and having to chuck the bottle I had just gotten not knowing there was going to be a frull screening since there was no warning) at YUL even though never left the terminal after landing. YYZ was just a passport check. This is not A/C's fault, but travelers should be advised/warned in advance so they know what to expect especially since you land and have access tot eh terminal and it's stores and food before you get to border check. If you have mobility issues, the distance can easily be a problem and there is no warning of how long it is until you have reached the end. My mom would not be able to navigate it and someone like her may not be able to stop in the middle of an empty long corridor to ask for mobility help. A sign offering how long (10 Min, etc.) the walk is like at new LGA terminals goes a long way. Also can be stressful if you're tight on time for a connection.

I’m 5’3 115 lbs and felt so cramped in this express jet. My carry on actually meets the requirements and still had to be stuffed Into the overhead and barely fit down the aisle. Not a great experience. Air Canada needs to replace these planes.

I liked that the flight was on time for departure and arrival

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.
