I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

Wonderful just hope the had more direct flights to Boston

Boarding process was fast and efficient. Short flight but on time and well organized. I would certainly fly TAP again.

Very long line at the gate, moved slowly. I had expected that boarding a flagship A330neo would be with a jetway directly at the gate, and not a long bus ride to the airplane.

The layover was only one hour and a huge line for passport control. If I didn’t cut the line and argue was every single official, I would’ve spent the night in this one. Obviously.TAP AIR people. do not take into account.this problem with their flight scheduling, which is extremely frustrating. Poor food choices, on the pasta was offered, they ran out of chicken right away. All the sodas and water poured in a tiny 70 mL cups, which is not enough to keep hydrated on the long flight. I had to ask for 34 cups at a time. Flight attendant seemed to be tired and overworked.

Very borderline, low budget airline without low budget prices There are no counts of soda, everything is dispensed enlarged bottles and poured into tiny cups about 70 mL so in order to keep hydrated you have to take 3-4 cups at a time. Also, there was only one food item offered, pasta, they ran out of chicken right away. Snack was very poor. It was called tuna sandwich, which is truly borderline. The flight attend attendance seemed to be overworked and tired.

I am not very tall, and had a difficult time getting my carry-on placed in the overhead bin while passengers were behind me waiting to get to their seats. After struggling with the luggage, I turned it around, and left it, knowing it was not properly placed, but believing there was adequate room for it in the bin. When the flight attendant came through the cabin, she asked whose bag it was, and scolded me for not positioning it correctly. She turned it around and moved on. I thought that her approach was totally unprofessional, calling out a passenger in that manner.

TAP‘s flight attendants seem to be among the least ambitious of all the international flight crews we’ve flown with. . When we left US and went to Portugal, and when we returned from Portugal, flight attendants were not very visible. Then did not offer frequent water breaks and when we had to go back to request water, I was almost an imposition. Meal quality was just average. The dinners were fine. Breakfast wraps were presented soggy.

There was no warning that they have added passport control after check in, the line was enormous and after 46 mins wait we missed our flight. Were forced to leave the airport and purchase new tickets at full price to board a later flight. TAP were unsympathetic and unhelpful.

Queuing for quite a while despite using the "speedy boarding".

Would not advise EasyJet for a 5 hour flight…small plane and hence a lot of turbulence. No inflight entertainment so struggle to pass time in cramped seats. We also fell victim to extra charge for our cabin bags, although bag dimensions were ok, but the handle was rigid and slightly fell outside their testing cage!!….never again will we fly with this airline and be party to their scams for making money!

The food and so are to expensive and old . Crew whas not very friendly . Apparently some other passenger can just Push through the waiting people to board while almost punching me and a father with a child down the stairs. Its always something with easy jet . The seats of row 26 where lose . And for a guy of my size there is absolutely no leg room at all .

Liked. The check-in was pretty quick as they had 5 desks working.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Boarding was smooth and quick. Flight departed on time. Equally evacuation upon landing was from both the front door and the back doors. Bags were on the conveyor belts before I got there. Excellent service.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Slow and delayed boarding, including standing outside 15m in -3 temperatures, Late take-off approx 45 mins Very slow bag delivery approx 45 min - no explanation

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

It would have been better if I was not ill so I didn't go and I didn't come back and I could not transfer my tickets to a later date as Ryanair stop flying from Manchester at the end of October till next year

Passengers next to me insisted I change seats so they could sit together. I had to frequently move so that when the sear belt sign was on I was in my proper seat! I was returning from helping my mum with my dad's things after his sudden death and didn't feel like arguing with the other passengers.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.
