Delayed takeoff was inconvenient. We should have boardrd later. Coffee/ beverage service on a 7:30 flight would have been good.

Flight from Lisbon to Barcelona was ok. Business flight Boston to Lisbon was awful. Attendants should pay more attention to Business Passengers and not be so stingy with water. Worse Business Flight I have ever taken. Food was awful. Cramped for space.

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Disastrous boarding. Entered air bridge only to descend stairs and enter a bus. Plane had insufficient storage, was old and chair recline was damaged. Air stewardess was sullen.

I wish to bring to your attention an incident involving a flight attendant that occurred on my recent journey. The attendant displayed a lack of courtesy, which was concerning. For instance, after accidentally spilling water on a passenger, the attendant dismissed the situation rather than offering a proper apology. Additionally, when I handed over my trash, the attendant reacted negatively because I placed a paper cup on the tray, she told me this doesn't go here and threw it back on my table. It was apparent that she was experiencing a challenging day, which unfortunately impacted the service provided to myself and other passengers. While I understand that everyone can have an off day, it is essential for customer-facing staff to seek support to manage personal stress without it affecting their professional responsibilities.

The flight crew was good, the flight itself was quick and comfortable

Boarding was late by 30 min due to a bus missing to take us to the plane... And then the flight was delayed by about 90 minutes, in a 60 min flight

Very agressive with bags both arrival and departures found minor damage to my luggage including my check bag being broken into nothing of value was in there so I do not believe anything was taken but definitely broken zipper into the outer pockets of suitcase

Everything was nearly perfect, and TAP staff were especially helpful when we missed our connecting flights and had to get on the next flight to Rome. The only aspect that could have been better was boarding: it was somewhat disorganized, which created a bit of stress. But in the end, everyone got on the plane, so the less-then-perfect boarding process did not take away from the overall excellent experience.

TAP Air makes you take a bus on arrival or departure, making it difficult for passengers to make connections.

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

The seats were uncomfortable. It was an old plane. The crew could have been more hospitable.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

I declined a wheelchair in Vienna as I was told it was a short walk. However, though I "boarded" the bus first, I was at the back when we got to the plane. There were steps up to the plane and no-one helped except the stewardess as I was near the top of the stairs. She found a better seat for me also.

Horrible connection in Heathrow on flight to destination. Flight missed due to delay on incoming flight. They did rebook us, and then that flight was delayed 2 hours. They don’t post gate info until 45 minutes to departure time which can cut it close if you have to take a tram to your terminal gate area. Then our return flight was completely cancelled. They notified us at 4:30AM. They rebooked us on a different airline and a different fare class. We were completely screwed. Travel day ended up being 30 hours. I will never fly them again.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

There's no inflight entertainment, plane was old, power USB didn't work
