Airline reviews

Cabin crew was terrific, even though they didn't come through the aisles enough between meal service to offer water or drinks. The quantity of video entertainment available was great, but the video screen was not good quality. Food served was sub-par for international business class. Absolutely no snacks were available between meal services, so i suggest bringing something in your carry-on. Most other airlines have some snacks such as small sandwiches, cookies, candy, fruit, or chips available for pickup at the gallery areas on intercontinental flights in business class.

Cons: "The plane arrived 2 hours late, causing me to miss a train from Marseille to Nîmes, and costing me money for an extra night's hotel that I hadn't planned (Marseille), plus wasting money for the night at the hotel that I HAD planned (Nîmes), plus the cost of having to purchase an additional train ticket for the following morning. The $7 voucher at the airport was nice, but honestly doesn't come close to making up for the cost and inconvenience."
Pros: "This flight was 11 hours and I could have lasted another 2 or so hours."
Cons: "The lady who checks paperwork for animals at the front desk with Luftansa Airlines was uninformed and didn't know what she was doing as well as unnessarily rude. MY large dog was on this flight and after several employees had looked over my forms for him she came out nowhere and threatened to not allow my dog on board due to faulty and incomplete paperwork! I instantly went into a nervous condition of the sweats and scrambled to prove her wrong. When I asked again what was wrong with my (actually legitame paperwork) she just told me that at this point it didn't matter and that she would allow me to fly even though I was at risk of quarantine aty destination. I wasn't happy about this and asked again why there seemed to be an issue and she was unhelpful, handed me a business card for the USDA and told me that I was lucky to get away with her travel mercies for my dog. I had visited a USDA certified veterinarian and she hadn't given me the opportunity to prove this. I was confused and annoyed and while the other employees could see this about me, they apologized on her behalf. I really wish I had gotten this woman's name and work station so I could follow up with her and inform her on a few things. Other than that I love working with and flying Lufthansa airlines!"
Cons: "Hi"
Pros: "The service was good. The food was average. I liked the complimentary wine."
Cons: "They lost my bag. Huge problem."
Cons: "Couldn't checkin online. Had to wait in line for over an hour."
Pros: "Excellent :) Thank you."

The boarding process was pretty much chaos.

I contracted COVID on the flight, since the passenger sitting behind me wasn't wearing a mask and was coughing the whole flight. Despite paying a premium price for "Economy PLUS", I still earned almost no frequent flier miles, and there was really no difference between this services I received versus if I had paid for the most basic economy option.

They required me to check a bag that would have fit in the overhead compartment, and the bag was lost in transit

Nothing. Everything.

TAP cancelled the flight from Rome to Lisbon, causing chaos in my whole flight back to US. Airline representative at FCO made all sorts of excuse not to work out a new schedule reflecting my biz class seat. Upon my insistance and declined they dis-service, I was finally put on Air Canada flight back to US. It was a very stressful process at FCO. I will never fly with TAP again.

The airline has lost my luggage.

Pros: "Smooth flight"
Cons: "More food, more water"
Pros: "New airbus neo great entertainment set up and comfortable seats . Excellent food in economy and very professional crew with personality"
Cons: "Economy fare was great until 95 euro for a single bag added to stowage was added on . With Ridiculously high baggage charges watch out if you are flying economy. Sort of negates the benefits of economy"
Pros: "Good movie selection"
Cons: "Multiple delays for my flight. First the departure was delayed which I know can happen. Then we boarded and sat for over an hour before take off. Captain made up a story about the plane needed gas and said we would take off in 15 minutes. An hour and 15 minutes later we finally took off."
Cons: "Flight to Lisbon late. Missed connection Now have 10 hour delay"
Pros: "The crew was really nice"
Cons: "The food and proving more snacks and drinks"
Pros: "The price."
Cons: "Starters, main course, etc where very odd combination of flavors and therefore not at all appealing. Don't provide beverage service in Business outside of meal times. Seats good but space is restricted. Feel closed in."
Cons: "They boarded the plane from both the back and the front at the same time with no direction as to which rows should go where. BIG cluster in the middle of the plane!!"
Pros: "Flight was canceled"
Cons: "Flight was canceled"
Pros: "Flight was on time, crew friendly on airport and flight. Plane was clean and sits were ok."
Cons: "The food could have been better."
Pros: "the crew did really made sure we had what we needed."
Cons: "Should have made an announcement that the 3g cellular coverage was turned on. Went on in the middle of the flight and had no idea. My phone was in the overhead bin and I thought it was off. When I landed I had an outrageous fee. Should be given a choice to use it or not."
Cons: "The check in process was chaotic and slow. At one point there was one woman checking in 3 lines of people for 45 mins before help arrived"
Cons: "Flight was so delayed we missed our connection."
Cons: "TAP was late getting the first flight out, offered almost no help and almost left 22 people stranded in Portugal and tried to get us to pay for a new flight at our own expense. Customer service was terrible. Multiple people in line said they had been stranded in Portugal by TAP airlines before."
Cons: "Good flight, on time. Service ok. Captain did a good job communicating. Nice touch with wine at dinner."
Pros: "Entertainment was fine"
Cons: "On my ticket I selected the lacto-ovo vegetarian meal and I never received it. I told the flight attendant and he said “we don’t have any more, chicken or fish”. I said “I am a vegetarian” and he gave me a tiny salad, a bread roll, and a chocolate mousse. I was very hungry as I hadn’t eaten in 9 hrs"
Cons: "Checked bag fee was expensive at $120 per bag. For the two of us bags cost $240. The plane boarded late this departed and arrived late. Otherwise a very good flight. Very comfortable, all Amenities worked, the plane was clean and the staff accommodating."
Pros: "Flight on time"
Cons: "No gluten free meal available"
Cons: "Schedule wrong, missed next flight"

Cons: "had the same food the third time this week. they could do more"
Pros: "Nice crew, tasty snack, new plane with comfortable seats"
Cons: "Huge bag charge for anything over 8 kg! Sign said last call 40 min before flight when agent told us to check board 30 min before flight for gate assignment!"
Cons: "Had to check 2 of our luggages, and it cost $95 per piece. Never flown an airline where I had to pay more than $50 per piece. Also carryon has to be less than 8 kg. Our small luggage that we had to check never had any problems with any other airlines about being a carryon but since it was over 8 kg, it had to be checked. Flight was short but no entertainment screen to watch or listen to music. Will not be flying with airline ever again."
Pros: "Food"
Cons: "Uncomfortable seats, too stiff."
Cons: "I did not like although my ticket had luggage allowance, TAP made my wife and I pay twice. Of course to pay needed endless and senseless wait and paying booth."
Pros: "Staff good very pleasant. Entertainment good."
Cons: "Bit late into Lisbon and luggage left behind."
Pros: "The food and flight attendants were very nice and accommodating."
Cons: "I had a 17 kg big baggage and a 7 kg hand baggage and was forced by the hungarian check-in attendant to pay the equivalent of 112 usd. I nearly missed my flight as nobody understood why I had to pay extra since my baggage was under - weight. Outrageous! Will not use Tap Portugal again and definetly won't recommend. Maria Petrita"
Pros: "Food, seats, flight attendants & in flight entertainment were all very good."
Pros: "The flight was quick, boarding was easy and efficient."
Cons: "Flight attendants can be a bit nicer."
Pros: "The fact that children were served first."
Cons: "N/A"

Cons: "Smooth flight food pilotes"
Pros: "The seats were very comfortable and there was a n extensive selection of great movies to choose from."

Pros: "The plane was newer and clean. The flight left and arrived on time."
Cons: "On a non- stop flight from Madrid to Portugal which I checked in 2 hours early for my bags and those of 15 other people were LOST.I did not receive my bag for 28 hours! They only deliver once a day. Additionally, they charge extra for everything you can imagine. Any weight over their limit is 105 euros."
Pros: "Lovely crew, nice breakfast, ON TIME!"
Pros: "Nothing"
Cons: "Flight was overbooked by over 20 people and even though we got the airport 2 hrs early to check in we were bumped from the flight. Next flight available was not for over 8 hrs later that day. Rude and not helpful employees. No gate announcement when flight was then delayed. Most American size carry one do not fit in overbooked head and was forced to gate check."
Cons: "I got food poisoning from the dinner that was served. The crew was very helpful though"
Pros: "Lots of leg room at no extra charge. The planes are new and very clean. The attendants were friendly and helpful. Food was acceptable."
Cons: "TAP can't process global entry at Logan international airport yet."
Pros: "Incredible experience!!! Best airline ever I have flown on!!"
Cons: "Only complaint was group lines should have been established before boarding began. Everyone was in a large group before they told us where to line up and then it was too late But once we were on the plane it was an amazing flight experience!!! The comfort was unparalleled to other airlines I have flown on. Thank you so much!!!"
Pros: "None"
Cons: "It did not included luggage cost which means i had to pay additional cost. You SHOULD state it in booking pages (NOT LINK). If i knew it i would never use TAP. I found direct flight, cheaper. I want you to pay back."
Pros: "Loved the customer service. Very friendly and helpful staff."
Cons: "The plane was making the strangest noises!! Something with the landing gear perhaps? Very high pitched noise. Also, the boarding was horrendous. No warning of the fact that we would have such a long trek to the airplane and in the rain, no less. However, I was grateful that we ended up taking a larger plane to accommodate all of the luggage. But then the stewardess had to spray something in the air around the bins, I found that to be very strange."
Cons: "The seats were not comfortable. It hurt my back."
Pros: "Good planes! Entertainment is modern, food good, service great. Boarding fast, planeson time. Special thanks to TAP taking off from Boston on 12/29/16 with snow and even heavy snowing. I was lucky did hey stuck in Boston. The only weird part was that i was not able to pick seats without a fee even 24 hours prior flight."
Pros: "Everything was perfect. More than I expected and would certainly fly with them again."
Pros: "Website, check-in, boarding."
Cons: "Seat pitch"

The ticket counter did not even open until 8:30 AM. They could not find our reservation even though we had a confirmation number. After about 20 minutes they finally found our reservation. They would not let my daughter and son-in-law book a seat online because they had an infant. So they had to get seats at the ticket counter which by this time there was not any decent seats left.

We were delayed leaving so we missed our connection. They paid for all of the travelers with us to get a hotel room but the hotel sold out and some people had to sleep in the lobby. All in all a pretty horrible experience.

Flight was awful. Team wouldn’t check our bags to final destination.

Nice job

Great service as usual thanks

The quality of the food must be improved Everything else is perfect

Sitting very tight less than what I expected beverage and snacks below par over all for relatively short flight ok wish other better cheap airline may have better service with less money

Great ride with excellent service

Service was great - flight attendants, on time, etc. the food was ok and the movie choices were limited…. But those things are minor in comparison.

On time Check in. That was not good after sittng in our sits, having been to change the places!

I wish there was ways to charge the phone while in the flight and that the service was better.

A few things, the boarding process was very bumpy and complicated with an interview and things that seems out of order. Once in the plane I think the entertainment was very poor. They advertise wifi, and tv programs as well phone signal and none of it worked properly. There was also no way to charge the phone or electronic devise while in the flight.

The seats are old and very uncomfortable and it felt dirty. The crew where very unhelpful and unwilling. They ran out of vegetarian meals and just didn’t care about it. It was just an awful experience.

Deplorable never fly again

Deplorable, never fly again

Is a big difference

Was very uncomfortable fly, chair to old and uncomfortable. People from my back pushed back the chairs the whole fly.

You screwed up on my flight, then didn't apply my meal choice to the airway so I didn't have anything to eat the whole 8hour flight. and whats up with the second piece of checked in baggage not being allowed? You should tell customers theres a baggage embargo.

you screwed up on my meal choice and I didn't have anything to eat the whole 8 hour flight.

Very rude flight attendance. No accommodation for special needs. Food is horrible. Very disappointed. Won't fly with ITA again!!

Aircraft was dirty af

The food

Very comfortable for this kind of airplane : Canadian bombardier

Boarding in the heat was not pleasant

More than 2 hours late and no food because of a problem with the catering. The flight was super full and there wasn’t enough space for the hand bags. A lot of space for improvement.

Main trouble was with Kiwi -- a partner booking organization through Kayak. Even though tI booked well in advance they did not assign me a seat and I came within a minute iof getting bumped from the flight. On the return trip the airline sent me an ominous message that I had to provide additional info before I could receive my boarding pass and that if there were problems I would get a refund. That caused unnecessary stress since the airline just needed my home address. Kiwi should have made sure they had collected all the necessary information from me before they booked my flight.

Long delay, lack of space at the seats (not comfortable).

We made the boarding and then waited inside 40minutes before taking off The plane was too full It was probably the worst flight of my life in terms of comfort. I was in the central seat, and on my right i had a very big person who was occupying part of my seat since he did not fit in just one. I think in these cases the staff should notice and do something about it. I checked if there were available seats by myself, but it was all full. Maybe in business class there were still available seats though.

Ecelent

Expect Full aircraft in economy

Meh

Sandwiches needed something like mustard

Short flight but easy

The ticket counter did not even open until 8:30 AM. They could not find our reservation even though we had a confirmation number. After about 20 minutes they finally found our reservation.
