Pros: "Crew was good."
Cons: "Plane was late"
Pros: "Comfortable flight, plenty of leg room and I live the individual chargers at each chair."

Pros: "Crew was very attentive and professional."

Pros: "Nice crew"
Cons: "Better food, some entertainment, better bathrooms"
Cons: "It’s an international flight. It is what it is!"
Pros: "Crew was excellent."
Cons: "n/a"
Pros: "My flight was delayed four hours, so I missed my connection to Sofia and had to re-book for two connecting flights instead of one, which makes for a long, tiring trip."
Cons: "I understand the delay due to weather conditions, but I wish I was rebooked for one, not two connecting flights. Now, instead of flying directly to Sofia from Frankfurt, I have to go to Munich first and then to Sofia, which makes my trip 9 hours longer"
Pros: "nothing"
Cons: "better accommodation of passangers"
Cons: "They told us there were no earbuds so recommended using our own. Our children had left theirs at home so they ran to get a $20 pair nearby. But the the plane DID have the buds; what we did not have were blankets — the crew said none were to be had."

Pros: "Baggage arrived with me. Upgraded to First Class because so many of those passengers got other flights the night before."
Cons: "Original 5 pm flight was cancelled because there was no Crew or plane, even though it’s a United hub. Though flight cancelled early, United could not get me home same day so provided hotel and meal. Next day flight scheduled 7:05 then 8 am, but even that time came and went without boarding. 15 hours delayed and no hurry getting the plane to depart at the stated time. Total lack of customer service and concern"
Pros: "Touch screen is sharp and responsive."
Cons: "Food is ok. Used to be better a few years ago when the cuisine had a Southest Asian fusion style."
Pros: "Cleanliness"
Cons: "It was late by 1 hour. Food was not enough. Was hungry since dinner was late due to delayed flight and breakfast was served at lunch time of MUC. Electrical outliets did not work in the flight and had problems in MUC for GPS."
Cons: "Water only and.. I had to asked for it. No snacks or other drinks in my eighteenth hour of flying back from Poland :(("
Pros: "Underseat AC power and USB power was the highlight of the trip."
Cons: "Food portions were tiny. Totally dehydrated at the end of the flight, and water was passed out in 100 mL servings. Insufficient space under the seat for a backpack."
Cons: "The air on the plane was unable to be controlled."
Pros: "I wasn't expecting free in-flight movies and meals, which were very welcome"
Pros: "Everything on the flight was very efficient and organized—the boarding process, the excellent and pleasant service, the food, and the entertainment selections. Thank you for making a long flight enjoyable."
Cons: "Food wasn't the best but did honor my special diet request."
Pros: "Impecable service. Even worth flying through FRA."
Cons: "Nothing. Everything, as always, great. Keep it up."
Pros: "The food was good."
Cons: "The seats were not too comfortable and the video screen was small."
Cons: "Walked a very long way in Frankfurf airport to transfer to another flight."
Cons: "Again 2 hours delay"
Pros: "SERVICE"
Pros: "They were nice"
Cons: "They were good"
Pros: "Service was very good, flight was very smooth"
Pros: "Restful flight"
Pros: "The service by the flight attendants was very good starting from the welcome to the end in spite of the fact that it was quite late night flight. Also by fortunate luck I had the chance to sleep as the next three seats to me were all empty in the middle block, which made the whole trip less exhaustive."
Cons: "If the seats next to me weren't empty and I couldn't lay down across all of them it would have been a difficult flight as the economy seats are not even close with economy comfort levels of other international airlines like Turkish Airlines especially the seat pitch size. Entertainment choices could be improved by more recent movies. There were very few selection."
Cons: "Not enough room. Aisle seat was too narrow and short."
Pros: "Better then United airline"
Cons: "Everything was awesome"
Pros: "On time all the time"
Cons: "Food getting worse year after year."
Pros: "Smooth flight"
Pros: "My parents had a wonderful experience. Very professional and courteous!"
Pros: "The agent at the counter was very very helpful and accommodated us to an earlier flight. That saved us lot of time."
Pros: "Fast boarding, on time"
Cons: "Too cold in plane, announcements too loud"
Cons: "Boarding three planes to three different destinations from the same gate is very confusing."
Cons: "It was too cold on the plane."
Cons: "We were in economy class. It looked like the seats my wife and I were in were smaller than the surrounding seats. The seat I was assigned was also more narrow than the one my wife was assigned. I am tall, and could not move my legs for the trip. Also, the seat controls were on the inside is the seat. I could not move at all without turning on the overhead light or screen."
Pros: "The crew was very attentive. I did not want to eat the food and the crew offered me fruit. Great A/V options."
Pros: "Short and Smooth Flight"
Pros: "They handed out baggage claim tickets for the larger carry-on items early so that passengers had plenty of time to rearrange their items, as long as they arrived at the gate in time."
Cons: "They had 3 flights boarding through 2 doors that led to one hallway, which was very confusing. It took quite a while to retrieve the checked carry-on items, with the effect that most of the passengers were lined up down the causeway tube, waiting. The seats are so very cramped on these puddle jumpers; this was way too long a flight for cramped seats that don't recline. The entertainment was wifi that never really worked."
Cons: "We missed the connection so never made this flight."
Pros: "Best crew ever. By far most friendly staff and excellent service."
Cons: "Nothing that I know"
Cons: "This was a united flight. The personal was not helpful, only in helping me communicate with the airport in Rome to change my flight. I had to pay 97 euros for this change. I am upset and think it is not fair that I need to pay for a problem united had with their flight. I also think star Allience failed as they were not able to resolve the problem with their partner airlines."
Pros: "When we fly Trans Atlantic, we always hope it will be with lufthansa! Sometimes they use united as a carrier and it us never as good as lufthansa!"
Pros: "Everything else was fine."
Cons: "I had paid for comfort seats ($140) extra. When I checked in at gate I was given another seat assignment (without explanation). It turned out to not be comfort seat, in fact it was the last row in the airplane. Had to get eh gate agent back, which was not fast. She said flight was full and a family had been spread out. I understand, but you can't just bump me from a paid and selected seat to a standard seat, especially on transatlantic flight after paying $140 extra. There was no apology. She went back to gate and little while later came back with a comfort seat. Some people seem not to have shown up as the seat next to me stayed open as well. It was very poorly handled."
Pros: "All is good expect confort and food"
Cons: "Food"

The food was not good and I felt that the crew was trying to save on drinks. Serving wine in a medicine cup was very cheap. Thanks

I didn't know anything about TAP Air Portugal but the flight was awesome and far cheaper than any other airline.

Great airline, took good care of us. Will use again if prices are good. Really enjoyed the 24 hr layover in Lisbon.

Pros: "Smooth flight"
Cons: "More food, more water"
Pros: "The flat bed"
Cons: "The Captain made loud announcements waking you up"
Pros: "I didn’t like a thing. The crew from the gate all the way to the end was rude and nasty. The crew scanning people to get on the plane were so rude at the beginning it was the worst and I fly for my work and I’ll never fly TAP air Portugal again."
Cons: "Train the staff to be nice and pleasant"
Pros: "Crew was awesome, seat spacing comfort not so much."
Cons: "Need to have seat upright to use trays to eat on flight"
Pros: "The crew was very friendly and responsive and the flight left right on time."
Cons: "The food was not good and there was very little in way of tv entertainment."
Cons: "Boarding process was in fact dangerous, with people corralled into small spaces without letting them out on the other end. We felt claustrophobic, crushed, and at one point people were even having to jump over the escalator to the bus loading area because there was too much crowding. Dangerous"
Pros: "Yes"
Cons: "Was exelent"
Cons: "Probably the most uncomfortable flight I have taken in a very very long time. The ride was smooth but the seat was so terribly uncomfortable. I was in pain on arrival."
Cons: "We had to pay $120 for a checked bag because it “weighed too much”. The lady at the check in counter said they were weighing everyone’s at the gate so there was no way to get around it This however was a lie and they were not checking weight and people got on without having to pay the outrageous fee"
Cons: "Wait time on buses from-to airplane to terminal was long."
Pros: "The only salvation was the entertainment choices. ."
Cons: "The planes need to upgrade the seats. When we were served food if the person push their seat back your food tray would flip like two did on our flight. Staff was jaded and sarcastic. I'm glad I had a discounted flight. I'd be angry if I paid full price. Poor staff, seat architecture, and poor food."
Pros: "Service"
Cons: "Coordination between connection flight"
Cons: "Too late with delay"
Pros: "Great food!"
Pros: "The crew were very friendly, a nice and relaxed flight and they gave out complimentary food and coffee which was brilliant"

Pros: "all staf in airport pleasant and quickly to across other place to connect"
Cons: "a lot of people they pass by preference, and late for star Alliance"
Pros: "Movies and friendly crew"
Cons: "Food was not good Too much meat"
Pros: "Clean plane, nice crew"
Cons: "No entertainment at all"
Pros: "It was quick."
Cons: "Delayed transport to flight, tiny non-reclining seats. Food offering mediocre and had to flag down flight attendant just to get water they we're giving to everyone but some of us apparently."
Pros: "On time!"
Cons: "That I had to pay for my check in bag on my return trip. Was told the ticket I booked didn't include check in bags. Whan my trip going to Portugal on Azores Airlines did. Someone shout step in and change this practice. Very confusing for the traveler"
Pros: "Very nice flight."
Cons: "Boarding should be more organized."
Cons: "When I booked the flight, your site said that I would not have a luggage charge, but I was charged 37 euros more when I checked in."
Pros: "Clean modern aircraft"
Cons: "Left 35 minutes late; had to take a bus to the plane in Lisbon (no gate)"
Pros: "Nice staff"
Cons: "If you are seating at the end of the plane they never have the 2 choice of meal and you are force to eat whatever is left, it happens more than once, seem to be the practice and is not fair to the costumer"
Cons: "I don't think I have ever rated any service negatively, but here's my first. TAP completely ruined my birthday trip that I have saved up for a long time for. DO NOT TRAVEL WITH THEM! I had a valid Schengen tourist visa issued by the Consulate of Portugal. At the time of visa issuance, the printer of the Consulate was not functioning, so part of the visa information was hand-written, but it was properly signed and stamped. The Consulate told me it's valid and said they have been doing so for ten years. The Consulate also said that they, not the airlines, have the sole authority to determine the validity of the visa. When I went to the airport to check in with TAP, TAP staff denied me boarding because they did not believe my visa was valid. I only learned later that this action was inconsistent with TAP's own internal policies. The staff at the kiosk told me that I could either ask for a refund or rebooking of the ticket. But when I called TAP the next day, I was told I could not get a refund even though they should not have denied me boarding. I called TAP many times and got a different answer each time. They simply refuse to compensate me for their own mistake. It's the most horrible travel experience I've ever had!"
Cons: "I have traveled to and from Portugal in TAP for many years and never ever did I have to pay for a checked bag till this year. It is totally a robbery to be charging people for 1 checked bag of only 50lbs. not only is it ridiculous but robbery. You charge a lot of money for the flights as it is and to go and charge people to check a bag on an international flight is insane. It is to bad I have to fly back with you because I will not be flying with you ever again after this I will take my money elsewhere. Also you need to let people know that they are being charged for luggage when the are booking their flight because when I booked my flight nowhere did it say I had to pay for my luggage. It already was rediculous that we are only aloud 1 50lb bag checked and now you want people to pay for it too? Pretty soon you minus well have people just get on a plane naked!!"
Pros: "75 Euro per bag!!!"
Cons: "I was told at the check in that my bags are NOT paid for...when I booked the tickets on line there was no mention of any additional charges, or option to purchase baggage"
Cons: "had to pay bag fee, though website said 1 hold bag was included!"
Pros: "Flight attendants were reponsive. Plane was comfortable enough. Good entertainment options."
Cons: "Plane was a little warm. Would have liked more information in English."
Pros: "Luckily had a 4 seater row for us 2 only."
Cons: "Delayed 3 hours leaving Lisbon due to mechanical failure. As a hub more planes should be readily available."
Cons: "Their short flight from Frankfurt to Lisbon was not that comfortable. Seats were thin, close together. My knees were jammed against the seat in front of me. Glad the international flight was more comfortable. Somehow we did not get the memo that there was a 0 baggage allowance for an international flight. Most give 1 or two bags free. So when we had to pay 80 euros for each bag it started off our trip with TAP a lot disappointed. We still have to fly back and we can go online and pay before hand and get it for 45 euros each. Increased out ticket prices by 205 euros. Will make me take a second thought before I book with TAP again."
Pros: "No issues, short trip, friendly staff, comfortable ride..."
Pros: "Hot food"
Cons: "easy flight,"
Pros: "the service from the crew was ok"
Cons: "The plane was very old for such as long trip. Seats very uncomfortable and no enough space to stretch your legs. the entertainment system was very old as well, so the experience for such a long trip was very poor."
Pros: "Left on time. Served food and drinks. Friendly staff."
Cons: "Served food and drinks. Orange "juice" tasted awlful. Bland sandwich. Seats did not recline."
Cons: "Terrible TAP service. Missed my flight to no fault of my own and I was made to buy a new ticket. No changrs, no partial refund, couldn't even use my return ticket which I had to rebook too. Nice customer service !!!"
Pros: "I gave up fighting with you and TAP to recover this error that was made a moment after I booked thinking it was to Brussels. I will think twice before ever giving Kayak or tap my business and blog you both to Facebook."
Cons: "The fact that it is impossible to speak to a human to correct this mistake"
Pros: "The plane and food. On my way to Lisbon food was terrible and plane was dirty, and uncomfortable. Also enetertainement was from the sixties. It all changed on the way back with an A330"
Cons: "Boarding 9s kind of cahotic and ground crew are almost rude."
