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!

Flight was delayed over 2 hours, then landed at a different airport!

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

great! appreciated the last minute upgrade to Comfort+ exit row, as well

The crew were very respectful. And also they were welcoming.they did help us locate our seats.i enjoyed.

The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.

Delta exceeded my expectations! I am beyond satisfied. Thank you!

Everything was very good or excellent, but the seats were extremely uncomfortable and painful.

We were delayed 2 hours because of a broken seat. Other than that it was a very nice flight.

an he late. super rude gate agent, to every person. spoke down at people.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

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!

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

Our flight was delayed almost 3.5 hours (some of the issue seemed to be weather-related, yes) but NOTHING was offered as an conciliatory gesture for this delay. No food offering or any additional drink offering. There is no entertainment is available on any screen behind the seats. The airlines are so quick to penalize customers for slightest requests for comfort- seat changes, complicated baggage allowances, seating zones which are utterly dehumanizing (ZONE 9? after Zone 4- why? This is so clearly meant to be a message to those that do not have 'loyalty' to this airline to make a distinguishing line in the sand. There is such a lack of humanity in the way people are corralled in and spoken to. So, I don't think airlines should be all that surprised when those some dehumanizing corporate treatment is returned to them when asked. The flight on the way into Calgary was scheduled to arrived at 9:25 and we arrived at 12:45 AM. It is not okay. I would think TWICE and possibly once more before booking with them again. Their overhead bins are small and limited so they bully you into either paying for a $90 checked bag or gate check a lot of people's bags. Often on their website there is no carry-on bag allowance. Beware!

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

It was amazing. From NY to MN crew members Jessica was very helpful when my son felt nauseous. She was extremely nice

Considering that our flight was changed to a day ahead and we were not properly notified, we showed up a day late and had a HORRENDOUS experience trying to figure out what happened and how to get home back to Canada from New York. After spending hours on hold with Westjet and Kayak, we came to the conclusion that we had to BUY new tickets to get home that cost DOUBLE what we originally paid. Not to mention a last seconr hotel room that cost $500 CAD for ONE night because of WestJets mistake. After meals and final costs, we had to reach out to our families for nearly $2000 CAD to get home. How was our return flight? We didnt get to take it...absolutely defeated and furious with both Kayak and WestJet who kept bouncing us back and forth on the phones with NO resolution. Unacceptable. We will be looking into compensation over this.

The plane was very warm and stuffy, overhead air jet running very weakly: disconcerting when Covid is still a real concern. ie: fresh air would be nice. On arrival, a 15 minute wait once the plane was stopped at the gate before the door was opened to let passengers leave. Then a 50 minute wait for luggage.

At the gate I got bumped from my reserved aisle seat to a window. Not a huge deal for a one-hour flight, but the "free seat reservations" are indeed "free" but not "reservations".

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.

Terrible - flight was flagged for fraudulent payment from being booked via Kayak. Requested to rebook with original credit card or provide new payment. Air Canada stay at JFK did not know how to process new payment. Had to fly from La Guardia 2 1/2 hours later instead with Air Canada.

Could not switch flights. No help from check in Four people doing nothing. Two hour wait on telephone but no other flights available. Overall experience sucked.

My flight ✈️ was delayed by 12 hours causing a disruption to my day

The flight attendant when departing JFK was mean and rude to passengers boarding

Not great tremendous delays instead of arriving at 8:15 pm arrived at 2:30 am next day no food gate changes. Etc

In flight wifi that I paid for was very slow and at times didn't work at all.

On July 1, 2023, I reached out to Air Canada via telephone. After a two-hour hold time, A representative called me back and asked me to confirm my Aeroplan account info. I used the account number, provided on my ticket. The representative told me the information I provided was incorrect. The representative disconnected the call without further assistance. I called Air Canada via telephone a second time and received a callback at 11:06. I started the conversation with the representative by explaining that there was an issue with my Aeroplan account info and the last representative hung up on me. Apparently, my ticket was assigned the wrong Aeroplan number by your own negligence. The issue was resolved by updating my parties' tickets with the correct Aeroplan numbers. Now back to the primary issue, I raised concerns with the new representative about the flight delays and cancelations occurring within the week prior to our trip. The rep assured me if there was a flight delay or cancelation, I would receive an email and be able to change my flight online. I expressed my concern about flying into Toronto and missing my connecting flight due to flight delays. (There were no available seats on any flight to Tokoyo on July 2 or July 3rd from Toronto.) The representative assured me there would be alternative flights out of JFK, taking alternative routes. I received an email notifying me of a flight delay to Toronto at 12:39 a.m. I attempted to change flights using the link provided. When I attempted to click on "CHANGE MY FLIGHT", your online platform showed a pop-up window that stated I needed to reach out to an Air Canada representative. Unfortunately, your service was not open at 12:40 a.m. I arrived at JFK Airport prior to 7:00 a.m. and waited at the terminal counter. Around 7:10, a rep informed me they would hold the connecting plane in Toronto. They even made a phone call to provide me with assurance. I then requested wheelchair assistance to get my 75-year-old mother and begin checking in our baggage. We checked our bags and headed up to the gate. Around 8:45 a.m., several passenger names were called including my party, to inform us they were no longer holding the plane in Toronto. We were informed to go downstairs to make alternative travel bookings. I requested wheelchair services to bring us back to the terminal counters. At 9:15 my travel party was told at the terminal counter there were no flights for us until July 4th or July 5th. I informed the counter this was unacceptable considering, I attempted to change the flight both yesterday and at the terminal counter this morning. They continued looking for a flight to Japan. They worked out arrangements to get us on a flight to Seoul and then to Tokyo, but we had to take it quickly. I agreed. After I agreed to this flight, the terminal counter informed me I would have to go to a different terminal and would need to take the terminal shuttle train. No wheelchair assistance would be provided. I canceled the trip!

The flight was delayed. They assigned us a direct flight instead, We are very happy with the changes!

My flight was delayed, cancelled and delayed again. I lost one complete day in Japan, a very needed vacation. My schedule / itinerary in Japan is now all screwed up. It will take more time and cost to resolve this. So, am I happy with Air Canada; NO!

Our trip to Spain turned into a stressful ordeal with cockpit issues and FAA air traffic disruptions. Our American Airlines flight from Raleigh to JFK was delayed nearly four hours, causing us to miss our connections to Madrid and Jerez. We were left stranded in New York with children, even running out of diapers while trying to sort everything out. American refused to cover hotels or rental cars, leaving us to arrange and pay for them ourselves. The delays also disrupted our prepaid rental car reservations in Spain. It was a frustrating and expensive start to a family trip we had spent months planning.

Very cold on board it was like having 16hours sitting in a fridge

Old dirty plane but great lie flat seats in business class

A crew member's attitude towards a couple passengers who couldn't speak English was rude. Just because they didn't understand what the passenger said, they were not given any snack.

Great. Clean. Seats comfortable. Food was free. Had new release movies.

The boarding crew was very helpful with a little special problem I had. The inflight crew - so-so.

They kept us on the tarmac for 6 hours after already delaying our flight by 2 hours. No one had any answers. They sent our gate checked stroller to baggage claim instead of giving it back at the gate.

There was a big delay and I missed my connection flight

I don’t like the music section but I believe it was a cost decision. I changed my flight last minute due to work issues and had to sit way in the back. The seats were way closer together than I would have preferred.

Our particular exceptional experience was with Johnny at JFK at check in. He was the kindest, most accommodating agent I’ve ever encountered taking extra steps to help my husband and I with our extra baggage. I hope that he knows how much he positively affected our trip.
