Airline reviews

Pros: "Super friendly"
Cons: "Maybe a hot meal?"

Cons: "We ended up with two center seats. Person in front put back her seat so I couldn't even fully unfold my service tray"

Cons: "Not cancelling it"

Cons: "Avoid Lisbon airport and TAP Air Portugal at all costs. A 1 hour connection at the inefficient Lisbon airport resulted in a 9HOUR DELAY. MISERABLE. Air Portugal didn’t allow adequate connection time."

Cons: "Not missing our connecting flight because if flight / airport delays."

Pros: "Seats are comfortable and room for pack pack under seats"

Pros: "clean and fast"
Cons: "use airport finger in Lisbon airport"

Cons: "A little too warm but not unbearable. We paid extra for seats together but did not get to pick them. We would have preferred a window but were in the middle 2 of 4."

Cons: "I arrived 13 hours late, had two extra flights. I was delayed 3 hours first flight, 1.5 hours second flight after watching two flights that I “wasn’t allowed” to be on depart right in front of me at 9 and 10 instead of the 11 that they rebooked me on. Once I landed in Lisbon after the second flight that o wasn’t supposed to take. We missed the connection by 5 minutes and there were many people flying to my same destination. I had to wait 5 hours in Lisbon when I shouldn’t have ever went to Lisbon. I bought a ticket from Newark to Zürich through Porto 10 hours in total. I think TAP overbooked everyone and seated us on purpose. The secondflight was delayed due to “bad weather” and it was perfectly nice outside. Shame on TAP. I’m sure other people are complaining."

Pros: "I’m taking offFlight was smooth and service was great."
Cons: "Flight was smooth and service was great. Long wait before taking off."

Pros: "Surprised and delighted to be served a tasty sandwich and fruit drink plus glass of wine on a 3 pm 2 + hr flight from Lisbon to London"
Cons: "Seats uncomfortable"

Pros: "Cancelled flight. Charged for bags even though we prepaid for them."

Pros: "Clean modern aircraft"
Cons: "Left 35 minutes late; had to take a bus to the plane in Lisbon (no gate)"

Cons: "The plane was very small service was not good and the crew were not that friendly"

Pros: "Boarding, crew, timeliness, choice of entertainment, modern plane."
Cons: "Food could be more inspired, legroom is limited"

Cons: "When the flight was delayed the people at the desk did not make an announcement about the delay, what was causing it and what we could expect. People waiting had to find out through rumors. There was no good communication. We also were unable to choose our seat and were stuck in the two middle seats when there were free aisle seats still available. My controller for the tv didn't fit back into the holder easily at all and my husband got a blood blister trying to force it back in. Headrest to hold my head didn't stay put to give proper support while trying to sleep."

Pros: "Flight was delayed leaving Newark so we missed our connection in Portugal which was supposed to take us straight to Venice. Instead TAP gave us a replacement flight to Madrid and then from Madrid to Venice A FLIGHT WITH TWO STOPS IS NOT WHAT WE WANTED OR PAID FOR. Madrid was also delayed and we missed our connection to Venice. We got a new flight from Madrid to Venice and had to wait 5 hours for it. A trip from New Jersey to Venice ended up taking OVER 24 HOURS!!!! Due to the disgraceful disorganization and service of TAP PORTUGA we missed our best friends rehersal dinner a memory we would have loved to have. Extremely disorganized, terrible customer service OH AND WE HAD TO PAY FOR OUR BAGS TWICE to get reimbursed later but I don’t believe anything Tap Portugal says so we’ll see. Staff advice did not align and they were unapologetic for the experience we received."
Cons: "Everything. The travel experience was a literal nightmare and not what we paid for. It’s criminal actually."

Pros: "Food was ok"
Cons: "The customer service I received was horrible horrible horrible especially from the check in counter the were very rude . After booking my flight on kayak I called TAP customer service just to make sure that everything was fine .I asked them about luggage they said I had 2 free and a carry on when I got to the airport said I had to pay for the 2 i said no told them that i called TAP they didn't wanna hear it i asked for the manager she I am the manager and you bought a discounted ticket and there's no luggage with this ticket only acarry on in a mean way if you want the you have to pay $90 for each I tried to call TAP can't get through them when they finally got through them the guy confirmed that I ve called it on the records but it said now it's too late to do anything I am already at the airport that I have to pay and contact them later. I wasted good hour and a half on this and I had to pay $180. After all that at the boarding gate they announced that they will call by zone .they called especial need called frequent flyers zone A never called zone B all they said last minute was this is the final call for flight #.... and I was right in front of them and guess who were the people making the announcement yep the same people at the check in counter"

Pros: "zero."
Cons: "bad experience- The personnal was not that good! Lack of manners! Bording was evryone for himself; people with children left behind, evryone got in, all at once. The food was very bad, usual it is good..I dont know if i would fly again with TAP"

Cons: "Friendliness flight attendees Service on board Equipment/ tv Food beverage service Language skills of flight attendants"

Pros: "It was a very comfortable flight and I love the dinner they served! Would fly TAP again."

Cons: "Poor entertainment"

Pros: "Fast boarding"
Cons: "Had to wait forever to find out Gate Number."

Pros: "Nice crew"
Cons: "No VOD No food available in between meals"

Pros: "I got to London"
Cons: "9 hour delay"

Cons: "My round trip ticket was purchased and in the confirmation it stated that it included one free checked bag. i also went online to reserve a window seat which cost 12.95. When I got to the airport I was told I had to pay 110 for my one checked bag as well as they had moved me to an aisle seat. Basically scammed me out of 122.95. I have complained with ygthe airline and if it is not resolved I will not be flying with them again."

Pros: "No power @ seats. No Internet, no spirits just wine and beer. seats are not padded enough for 7 hour flight.. Old equip."

Pros: "Entertainment sucks! Monitors are small and poor quality view. Fixed settings for movie options. Shut it off and went to sleep. Seats were too tight and no knee space. Food was ok."

Cons: "The delay on the take off"

Pros: "If your traveling with a child they are the best! Legroom was good, seats were confortable, and entertainment system was great."
Cons: "Breakfast was terrible but I guess I'm lucky the served it. Didnt like that they changed the baggage policy after I purchased my ticket and wouldnt honor the old."

Cons: "We had to postpone our first leg from London to Lisbon by a day and then they cancelled our return flight without telling us!!! So, we were trapped in Lisbon with no flight to return home. We called them and they said, "we cancelled your tickets and only have business class seats available for you and your toddler." We said no thank you. If we were going to spend 1k on a return flight, we were going to take British Airways. TAP, never again."

Pros: "Food was interesting and pretty good. Seats were okay. We were happy we choose tap"
Cons: "We never saw a crew member smile. They verged on being surley. From the time we boarded they were yawning. I do mean all of them were acting uninterested in doing their jobs."

Pros: "Seats were comfortable with plenty of room between you and the seat in front of you. Huge plane. Very nice."
Cons: "My video screen did not have English available"

Pros: "On time, no mishaps."
Cons: "Entertainment system was very old and only partially working."

Pros: "It was a good flight overall."
Cons: "Boarding went smoothly, the food , beverage , and the entertainment was good."

Pros: "Friendly crew. Good info on delay"
Cons: "No offer of coffee in businesss when woke up. Still 35-40 before landing"

Pros: "Some staff were helpful"
Cons: "To start off our trip we weren't allowed to get on the plane until an hour after our boarding time. After we were allowed on, the air conditioning was not working and continued to sit on the tarmac not even leaving our terminal for another two hours. Within this two hours there were many elderly people asking for help and one specific gentleman whom was in his late 70s, informed the people around him that he had a pacemaker was pleading to get some air conditioning to the point where 6 people on the airplane were fanning him off. It was 90 degrees in the airplane and we had been sitting in the plane without any help even pleading with the attendents to let the elderly off so they did not pass out. Once we reached the 2 hour mark without any ac the gentleman in his late 70s was beginning to lose consciousness and many people had to call the emergency services, and the crew on flight TP214, tried to tell us everything was fine while the plane was pulling away from the terminal ... as they were giving the man oxygen, even though the elderly gentleman had lost the ability to communicate verbally and was about to pass out. They had to pull the plane back off the tarmac fully delaying us 3 hours in the process making us miss our other two flights. Once we were finally in the air for the 6 hour flight our entertainment system was not working so we were left to twiddle our thumbs for the remainder of the trip. It really ruined what seemed to be an exciting trip and I highly doubt we would ever take TAP Portugal ever again or recommend it to anyone no matter the price."

Pros: "The seats were comfortable, but could use a bit more padding for a long flight. The food was decent, and there was a good assortment of movies, music and TV shows."
Cons: "The crew seemed unhappy to be there."

Pros: "Everything was perfect! The staff was friendly and the food was nice. I found that there was more leg room than on other airlines."
Cons: "I used TAP to depart beautiful Portugal."

Cons: "Missed that flight because of previous delay"

Pros: "The crew was super nice and professional"
Cons: "The plan was delayed 2 hours, seats were beyond small."

Cons: "Entertainment system wasn't working and will restart itself during 10 minutes EVERY 10 minutes. Very inconvenient. The flight attendants were impolite too."

Pros: "The flight was fine, no issues. Plane was fine, no WIFI or entertainment. Served a small meal. For the price, excellent trip."
Cons: "All was good."

Pros: "Had all the wine I could drink."
Cons: "The flight was too late for our connections."

Pros: "The on-board crew was pleasant and professional unlike the check-in staff. Food was ok, landing was smooth."
Cons: "The airline makes money by having very low weight allowances on carry-on and checked luggages. The staff at the check in desk act like they are surprised and symphatetic about the overages meanwhile they enforce the weight limits to the gram. Most deplorable of all is the fact that they have one person on staff at a special desk where one can go to pay for the newly discovered overages. This desk and the person assigned to it full time is the proof that the company expects this kind of result before hand. Where on most continental flights the weight limit is usually set at 31 kilograms for checked-in baggages TAP Portugal has a limit of 23kg. Where most companies have no weight limit or around 20kg on carry-on baggage they have 8kg. The overages in weight result in a flat fee of $100 per luggage, even if the luggage is just one kilogram over the allowed limit. The low ticket purchase price is in my opinion a deplorable marketing scheme aimed at getting people to buy their tickets and then be faced with extra charges when it turns out weight alloweances are set at domestic standards."

Pros: "Ask persons for veg or non veg snacks before u served please."

Pros: "Lots of flight options."
Cons: "Both outbound and inbound flights late, no real explanation for inbound. Boarding on inbound was chaotic."

Cons: "Rude staff."

Pros: "The wine"
Cons: "The entertainment platform was on the fritz the entire flight. Almost all the headphone jacks didn't work or were shorting out. This plane had the two prong headphone connectors so you are forced to use their terrible plastic ones. The legroom for an international flight was terrible, almost the same as Spirit Airlines in their economy class. The food was very bad (dried beef with noodle) and cold by the time I was served."
