  • No matter which airport in Canada you would like to fly to, you should be able to find nonstop flights.

A few improvements: 1. No signages at the airport that the porter airline was a codeshare and i could check-in at American counter. 2. Crew at the gate said they couldn't change my reward to Alaska - despite that being done previously 3. Despite there being many open seats, i was assigned a seat at the very back near lavatory, last row. Fortunately, the pilot wanted more people moved up so the flight attendants moved me up. It seemed very odd to have been stuck in last row with very few people nearby..

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!

Much roomer than air Canada! Great flight for the price. No complaints

As a first time flyer with Porter I was happy with the service and comfort of the airline.

Other than wifi no on board entertainment. Will use them again, roomier seats than other airlines and snacks and beverages, better than average

I like it, but the food isn't good. They need to offer more simple things. This bowls that have so many things your don't know what your are eating. The milenials like it, no the rest. And last but not least, they allowed somebody have a huge dog, vey agressive and fidgety in the flight. That's horrible. No animals should be allowed inside the airplane, what about allergies, etc

The flight was half empty yet they charged me $50 for a basic carry on! I saw how passengers of different colors were treated differently.

There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

travelling in 14th of April and now we are in 17th , I have not received my lost/delayed bag... this is very bad and the worst part is their call center is not able to see where is it!!!!

Boarding was delayed by an hour and then we proceeded to sit on the tarmac for another 30-40 minutes. No clear explanation was ever given and the delay caused me to miss my connecting flight home. Was forced to stay the night in the connecting city which impacted my following workday and cause personal issues at home as well.

Good flight — left on time due to on time arrival of Pittsburgh flight

Delta keep on impressing me. Right now Delta airline is the best of them all

Good but since we got in early we had to wait on runway for our gate. That was kind of a bummer but we still got in earlier than planned For entertainment I was watching a movie and getting close to the end of it with 15 min left but it kept jumping automatically to the next movie before finishing.

13 hour delay stuck in Detroit and missed a day of meetings. It was terrible

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

The cabin was definitely dated, but that's about par for the course. The flight crew were wonderful as always (always a Delta highlight), but the boarding process was slow with little direction or encouragement to get people in their seats quickly since we were already delayed.

Totally organized, quick boarding, professional staff and ON TIME! Good size seats in the cabin Wonderful experience

The flight was delayed to board, then delay in landing and extremely bumpy landing.

Could have been on time and not missed my connection

⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Great, except the canon was so cold. Even the flight attendants put jackets on

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Flight got cancelled and there was no communication to mention the rescheduled / alternative flight details.

Our flight was delayed 3x and we were unaware until 15min of arriving at the airport so had we been made aware sooner we could have enjoyed possibly another 4hrs poolside. Very frustrating. Made the next day going back to work extremely tough too.

It was ok. Jet was ok but it lacked many convinces we have experienced on other airlines such as in seat entertainment. Space seamed more compact than other airlines. They did not provide the gate to gate assistance we arranged for for our mom who needed a wheel chair.

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Flight was good, crew was excellent. No complaints at all

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

Liked they had tv screens on plane but no service for drinks and a snack when other airlines do

The plane was very cramped and no room to move. Other passengers brought suitcases that didn't fit in the overhead bins. This made boarding and departing extremely slow.

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

I had a good experience. I liked being informed about the status of my luggage

The staff could have been friendlier. And Having the flight on time would have been much more convenient.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

I was forced to check my carry-on bag, which I don't appreciate.
