It was okay overall, but it was a 4 hours flight and the only thing we got was snacks, I really expected breakfast.

It was okay overall, but it was a 4 hours flight and the only thing we got was snacks, I really expected breakfast.

Keep better track of bags. Not sure how they got lost. Also not sure why it took two weeks for us to get them back. Had to buy a bunch of necessities because they were packed.

food worker strike caused lack of service. I know, not your fault but a bit of a inconvenience.

The staff on the WestJet flight were friendly and helpful. The flight was smooth and we arrived 30 minutes ahead of time.

not as spartan as an air Canada flight, less comfortable / no in-flight screen as compared to similar priced Air Transat flight. Crew Cabin were professional and approachable. They got the job done, safe flight, on time despite delay in take off.

We requested 2 wheel chairs upon arrival. On board an attendant told us to remain in our seats until everyone was off the plane. we were in row 11 and thought we would be off early. After all were off, a different attendant said we should leave, and that the chairs were gone. One was available for my friend who had just spent 9 days in hospital but I had to walk quite some distance. Eventually a cart arrived to take us the rest of the way. This was over an hour after our arrival. The staff at the terminal did their best to help us but if we had been allowed off with the other passengers, our ride home would have been an hour earlier.

There was no entertainment and no announcement till well after I and others asked about it, and no "compensation" (like a free snack)

4 hour delay, lost our bags, staff was loud and it was an overnight flight

Entertainment was the only issue. I did not have app & not equipped to watch movie on my phone. Used to other carriers with access to a screen for viewing. Other than that, everything was fine.

Great flight. Pilot was able to fully make up the 42 minute late arrival of the aircraft for an on time arrival in Toronto.

Wish we had music during take off and landing like the last flight

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.

Crew is ok. They offered food n drinks. Had difficulty connecting to wifi on board.

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

Great. Porter is very efficient, welcoming, and organized. I fly Porter often.

Flight was smooth and comfortable. The crew were exceptional. Amanda, Nichole and Hershel were attentive to our every need. So friendly. My daughter and I were surprised at quality of service. Loved the double row seating. Snacks were delicious. We would definitely fly with Porter again. Flight PD 670 SFO to YYZ Thank you so much for the best flight experience we have had

The E195-E2 is a great aircraft! Leather seats, lots of legroom and SO quiet! The flight crew is terrific!

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

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.

Flight delayed 6 hr. Looking for compensation and will claim for it.allow US people to fix to avoid huge delay having a canadian tech to fix it.

Why does it have to be painful to fly long distances?

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

On time take off…US cabins look tired and need of refresh!

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

Flight was on time early arrival better entertainment good staff.everything was excellent

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

Due to a strike taking place with the airline, it negatively impacted my flight in multiple ways. My flight was delayed over 2 hours and the food served was mediocre at best.

Cabin crew were great. Seats are criminal for tall people

The fact that I got to Toronto alive and well and safe is a huge plus. I thank the captain and crew for a safe flight The comfort of the aircraft leaves much to be desired. Human beings should not have to be that cramped and squashed on a flight that we pay a lot for and even have to pay for lousy food choices The cabin crew were pleasant and helpful Kudos to them as the flight was packed to capacity and there was a lot of work for them in a short space of time All in all a good experience, but too cramped

The trip was fine and uneventful. The seat in business class was very uncomfortable which was disappointing given the extra cost. It was spacious but it felt like I was sitting on metal bars. The food in business class wasn't very good. The flight was ahead of time, the staff was professional and courteous and our luggage arrived safely.
