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.

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

The whole experience from check in to deboarding was fantastic.

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

Great! Personable crew. I love that they pour complimentary beer and wine.

I love the 2 seats per row. More room. The crew were excellent.

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.

The plane was pretty full, and we dis not have any includes meal for our 4h30 flight? And on-board entertainment wasn't available, there was no TV or plugging to charger your device on the plane. They told us to download an app if we wanted to watch movies but it never connected, that was a disappointment, the r we st was very good though and the crew were really nice!

Seats were very tight especially for first leg of trip.

Not necessarily a Transat issue but it took 2 hours to go through immigration. Tried to reach out to Transat for resolution but was unable to reach an agent.

The flight was excellent, once it started, however we were delayed two hours when the first plane’s engines wouldn’t start. They found another identical plane and transferred us and our luggage in under two hours and made up almost an hour in the air.

Really low cost trip for the huge amount I paid…o paid 550 dollars just for the trip, one way trip, plus 95 for 1 luggage’s and the second 135 dollars…no blanket, not headphones for entertainment, food was served after 3 hours and 2 hours after, breakfast was served Bad, low cost company for high prices

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

Aircanada was not great. Didn't get anything to eat. No snacks. No entertainment. Horrible checking in.

My return flight experience was one of the worst times I have had traveling anywhere this year. Not because of the flight. It was because there was not enough time allocated to deplane, go through U.S. Customs and U.S. Security to get to the gate for the connecting flight to Boston which I missed, There was well less than an hour between my landing in Montreal from Prince Edward Island to my connecting gate. I even called Air Canada on the morning of my return and noted my concern over the short layover time, not more that 45 minutes. The initial flight was four minutes late. I was seated in the rear of the first aircraft, and it took at least 20 minutes to deplane. The U.S. Customs was a considerable distance from the gate at which we landed. The need for double security seemed unnecessary and redundant. The distance from the security to my gate was again fairly great, and the wrong gate number was listed on my boarding pass. The agent I approached at the flight that was going to Newark, New Jersey was too busy to answer my question as to what gate was for Boston. When I got to the right gate, they had just closed the door to the aircraft even though I arrived a minute late. If I knew the distance to Customs and from Security to the gate, I would have asked for a seat on the next available flight which was 4:30 pm. When I made my call at 6:00AM that morning. When I asked the agent at the Boston gate, he said that the 4:30 flight was already “OVERBOOKED!” I was put on an 8:30 PM flight and didn’t get home until MIDNIGHT. I then had to care for a barnful of hungry animals and didn’t get to bed until 2:00 AM.

From Montreal to Cincinnati the flight was perfect! Flight free and everyone was perfect and a pleasure to travel with. But from Casablanca to Montreal the flight crew were quite cold, unhelpful, also seemed to scold many passengers instead of simply educating or instructing them. There were a couple for sure I could describe but not name… i was really shocked bc my experience w air Canada is typically a good one at the very least. It seemed something was very much so I’m the air w the crew. The two older lady crew members and the male were amazing but the younger lady crew members w the exception of one were very clique-y and snarky, sassy

Seating wasn’t too cramped; I don’t understand how luggage bins get full if there are enough for each person. Shouldn’t there be room for the designated carry-on and personal item for each passenger at their seat? THEN, IF for some reason extra room is available for someone who prefers it, then shifts can occur. I’m simply saying it seems that I should have primary access to the storage bin at my seat and underneath in front of me. It was suggested that I go to the back of the plane to store my carry-on when I paid to have access to the first seat after 1st class. The additional stress and inconvenience could be avoided and I think all passengers and flight crew are interested in guidelines that are fair, clear, and reduce tension.

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.

Took forever to depart parked on the runway for ever after three departure delays. Could have walked...

It was 3 hours late and ruined my plans at destination. Also rough landing.

Flight got canceled last minute and rescheduled 3 days later, as if we do not have jobs and children to return to. 5+ hours on hold with customer support with no answer. We booked a different airline and spent 3x as much to escape Montreal bc of Air Canada. Still haven’t heard from them. Boooo

Seamless! Long but the seat back entertainment kept us all busy the whole time! Meals were excellent! Crew fantastic! Very attentive!

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.

boarding is so disorganized, i was literally appalled at the boarding experience

Comfortable but not Polaris or Delta comfort Business Class. Overall 7 out of 10

Tap air Portugal was the best I will traveling again with u guys. Thank u.

The long wait at JFK made the trip horrible. Also not having enough buses when we deplaned was annoying

Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

I’ve never had worse food in business class ever!

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.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

The flight was ok, the flight attendants were lovely, the movies were good, the food was ok, and I am just sad because my luggage didn't arrive with me in Iasi because the flight from Vancouver to Frankfurt was delayed and then I barely made the rest of my flights. Also, there was no real support once I got off each of the flights. There was nobody to ask about gate or where to be and for example when I got off in Vienna to catch the flight to Iasi there was no screen where I could read the gate and time of departure of the plane. I was going crazy trying to find the plane to Iasi and I barely made it. When my luggage finally arrived home it was broken. The handle was completely broken and that was not so good. I am in a visit here, in Romania, and I will have to buy a new luggage.
