Airline reviews

The flight crew was top notch. Total professionals, they worked to help everyone fit their luggage on board and get comfortable. Like many European airlines, dinner service included wine with no extra charge. Always a nice touch. On our layover, everyone needed to clear passport control, which looks like a horrible time sink when you have a connection. My compliments to the ground crew who tried to move people with tight connects to the front of the line. I don't know whether they were Air Portugal employees or not, but they were some people's heroes. I'm not a fan of airline pricing that doesn't give you a reasonably realistic idea of your total cost. Checked baggage on Air Portugal is very expensive and negates any other price advantage. Seat selection is also quite costly. My biggest complaint about this airline is their boarding process. There is no info available to passengers on the screens in the boarding lounges. Just long lines that stretch into other gate areas and too few people offering any clarifying info at all. Those who try to direct often ended up yelling into the crowd. On my last leg, they called for boarding groups over the PA system, but when I presented myself, I was sent back to the end of the single line even though others in later groups were ahead of me. It was a confusing mashup of two systems that left everyone disgruntled and took over an hour. I don't think I can recommend this airline if you have any other options.

Efficiency was great - on-time takeoff and landing. Baggage arrived at destination (there's always slow baggage handling in Boston.) TAP food is spartan - bring your own. But the efficiency of the airline more than makes up for the mediocre cuisine.

Most important was the effciency - on-time take-offs and landings, no missed connections, baggage arrived correctly. Friendly & professional crew. Less important was food/drink. Pretty spartan, but we'll know next time and bring our own stuff.

Great airline, new, comfortable and quiet planes. Plenty of leg room and state of the art entertainment system. The big downside is the connection in Lisbon. The airport is small and a bus is needed from the plane to the terminal. Is a mess, takes a lot of time, nobody gives an explanation, boarding zones are not honored, etc.

People seated in exit rows should have designated overhead space

Larger seats on this plane made the ride reasonably comfortable. Our next flight, from Lisbon to Copenhagen, was inconsiderately tight and stressful. The seats were smaller, space between rows was very limited (no button or mechanism to even slightly incline anyone’s seat), and leg-cramping under the seat in front. Just like sardines in a can. Really felt for all the tall Danes on the flight. Their knees were pressed against the seat in front throughout the flight.

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.

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

Two of three flight attendants were not super kind as I would expect. The very kind young lady in my section was wonderful but then lady and man up front were not. Sorry but it makes a difference !
