There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Referencing ANA'S service to Japan and the return on UA, the pillow was awful, the crew was not very attentive, and the food was bizarre and tasted okay. Whoever's idea it was to make vegetable tempera in a steam capsule should probably revisit that. Since it was the vegetarian option, it was my only choice.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

I paid $7,000 to fly round trip to Porto. I thought it was for business class. But on the leg from Miami to Newark, and again from Newark to Miami, i was in coach. One time in the middle seat of coach. From Newark to Porto I was in business class as expected, and it was fine. I fly to Portugal once per month, often paying $5,000 for business class. Usually i fly American Airlines. I'd be happy to fly more with United Airlines. But my experience was disappointing because i was put in the coach for almost half the flights.

Checked my bag despite paid the seat upgrade and there was plenty of space available in the overhead bin.

The flight crew was fantastic. The flight attendants were incredibly considerate, kind and attentive.

The flight from Lisbon to Newark was much, mush better then flight from Newark to Porto.

Didn't make announcements during boarding, flight attendant seemed annoyed when I asked for water. Too many hours between flights. Confusing check in at the Lisbon airport.

Delayed at the beginning and the end and almost missed our connection

It was a good experience overall. We were however delayed by over 3 hours due to a security issue with one of the passengers inadvertently leaving a power bank in a luggage she was using as carrying on but then had to be moved int check in due to spacing issues. The airline staff had requested that she checked her bags in, but should have reminded her about removing all hazardous material like her power bank. When she eventually remembered as we were on the plane, we had to turn back and go through security all over again. Hence delaying our takeoff. The incident could have been prevented if staff reminded these passengers to remove their power banks.

Great price for really nice seats and the plane and staff were great, only 5-10 minute delays!

Terrible flight attendant attitude. Average 3-star hotel employee has better hospitality skills. Business class seats are literally a joke. TAP executives should ride business class in other airlines to develop some rudimentary sense of what business class is.

When I tried to enter my identity details, your app told me information was missing but did not highlight the missing data. This was frustrating. Also, there was an unexplained delay of about 2 hours in taking off. This was also frustrating. Otherwise the experience was good.

The flight was delayed without any type of notice. After passing through the gate, people were lined up at the passages boarding bridge standing for about half hour with no clue when they can board after ‘boarding’. No explanation or indication of the new departure time. All you can do is standing up and waiting.

The tickets were economical but the catch was the exorbitant baggage fees. So sketchy!

Food was bland..... Boarding priority mess with being bussed to plane. Newark baggage took 45 minutes to hit the belt.

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.
