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.

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.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

On time - really well operated flight. Friendly staff. Super impressed with United on this round trip.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

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

The flight had maintenance issues eventually resulting in cancelation. Additionally, the staff on the ground was not helpful to assist with rebooking the flights resulting in an overall unpleasant experience and we missed a family wedding due to the cancelation.

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

Crew were fabulous, motivated and sincere in their connections. The chairs need reupholster as they have lost their stuffing lol Food was meh. Most of us have to eat healthy these days. Really impressed with the staff

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.
