Poor landing as we overshot the runway and had to re land the plane. Lost both of my luggage not found as of yet. Had to pay extra money for my luggage in USD, now great my luggage is gone. Will not fly with Porter again.

This flight to St. Johns was really good. Boarding was a breeze. We left spot on time. Seats were actually pretty good. Recliner further than I expected. Three more flights to go we will see if this is the status quo for Porter.👍

I was not happy with AirfareAssist, the agency that kayak advised me would be handling my booking. I was advised by porter airlines that I had been overcharged for the Basic express , a option that I had asked airfare assist to help arrange after I realized that the basic fare I had chosen with porter did not include a carryon. At each checkin porter advised I had been overcharged for this . They advised that money would be refunded to my credit card, however, this is not likely to happen as it is not my name and credit card that appeared on the porter invoice, but that of another individual/agent. When airfare assist was arranging the basic express with porter on my behalf, they asked me to confirm that I agreed to pay $263 USD for this. I did agree, as I was advised this was needed to proceed. When I checked the invoice on the porter website and saw that it was not my name and credit card on the invoice, I was advised that this was how airfareassist processed the payment. The Porter invoice indicated a billed amount of $126USD I will not use Kayak or their designated AirfareAssist again

Our flight was delayed by a bit. I appreciated that we were kept informed on why periodically. Boarding was fine. I overheard one flight attendant sounding very rude to a passenger who was not paying attention to the safety demonstration. The snacks were minimal as it was a short flight. There was no entertainment. Overall the flight was good back to LGA.

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

The flight was fine see earlier note for the problem

All good the seats a little tight and no I pad screen

Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

The crew were polite and courteous. The Pilot did an excellent landing. It was very smooth and gentle. My only regret is that I was charged twice for my luggage . The attendant gave me no receipt . I didn't realize until I was about to board. How can this be resolved? Thank you.

Very smooth flights Toronto to Rome and return. Crews were great, food was fine but very narrow seats and limited leg room. Aisle seats on our return helped with a bit more space.

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

It’s ok just the boarding point is far too far

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

An old airplane with very uncomfortable seats in the Comfort “class! Small, narrow, and hard seat. Entertainment options are inferior, old movies. Boarding started at the back of the airplane, as we entered the aircraft last instead of after business class, risking the possibility that the comfort section would not have room for carry-on in the overhead bin. The food was ok. White wine was terrible. Overall, the flight felt worse than cheap airliners, and the price was as high as premium carriers.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.

I had a business class ticket from EWR to Madrid with a layover at LIS for 11 hours. It was obvious that I needed to pick up my luggage in Lisbon for 11 hours and check it in again when boarding the second flight to Madrid. Before buying the ticket, I called TAP customer service. Customer service assured me that I could get my luggage in Lisbon. When I arrived at Newark airport, I immediately asked to check my luggage to Lisbon. However, the TAP employee refused me, saying that I should resolve this issue upon arrival in Lisbon. She checked my luggage to Madrid. I asked the TAP employee at the gate to help me when boarding the plane, I asked the flight attendants manager on board the plane to help me. All the employees refused to help me and said that I should resolve this issue in Lisbon. It took me 4 hours to resolve this issue in Lisbon. I arrived at 11am and they didn't give me my luggage until 3pm. As a result, I was so tired after a sleepless night on the plane and 4 hours on my feet at the airport and all my plans were ruined that I couldn't fly to Madrid. It was a terrible experiance,

The seats were not designed to comfortably see people in coach for more than 10 minutes

A good, comfortable flight with friendly crew and good entertainment options.

Very rude person at the boarding desk; flight attendant coughing 3 inches from my face three times- not even covering her mouth; boarding process very unacceptable for older people with stairs to all planes (are you all stuck in the 1960’s?). I am sure that I am not remembering all of the negative things, but I am sure you get the message!

There was chaos at the Naples airport. We arrived three hours early for the flight but there was no invitation available about where to go to check bags until an hour later. Then we had to go to a different terminal to check our bags and check in and back to the first to board.

We flew TAP last October from Newark to Lisbon. The meal was bad. This flight had good food. Also, this flight was delayed. There were TAP employees waiting at Lisbon to make sure we made our connecting flight. I find the TAP website and app frustrating, but the service once we reached the airport was very good

The airport temperature at the airport and on the flight was too warm

Boarding too way too long. Biggest peeve: zero in-seat power in economy! No plug sockets, no USB ports. Plane was an A330, so not old.

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

I ended up in Lufthansa to Zagreb because of our delay

Not bad. We had preboarding tickets but the preboarding was badly managed. We lined up behind all the parents with little kids etc and when we got to the front of the line the attendant deliberately turned away from us and ignored us until I asked to be allowed to go to the gate. She started telling us that we had to wait until I told her we had preboarding then she let us through.

Everything was perfect. That is the most beautiful flight over thenDolomites.

Everything well done and customer oriented There entertainment system is difficult to navigate

It was good service. The very low economic seats where not comfortable

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.
