Airline reviews

Food is poor. Drinks in dixie cups, only white/red wine in Premium Prime despite business class food-which even that is a joke. Second “meal” on a 12 hour flight is a bagged sandwich in a cardboard box, which on premium airlines is a snack served BETWEEN meals. The premium economy product has some good parts but is obviously a cheap way of somewhat upgrading economy without actually putting any money into it. Lisbon airport is overcrowded and almost 3rd world as an airport. Crew is efficient but militaristic-crrtianly not “warm”. Entire experience feels like an intercontinental budget airline.

Excellent! Flight left a bit late but overall a pleasant experience.

Business class seats aren't comfortable. Food was not good.

They left our luggage uncovered on tarmac in pouring rain during an hour delay of departure! At our final destination, we found ALL OF OUR CLOTHES/SHOES soaked all the way through!! Our 1st connection plane was a great business class accommodation but only 50 minutes long. Our 2nd connection from Lisbon (another delay with luggage uncovered on tarmac) had only the extra legroom and mediocre food in business class - no entertainment and no extra comfort seating. Will not use TAP Air Portugal again!

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 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.

Flight from FNC to OBO was cancelled. We were rebooked to Lisbon later in the day. It was inconvenient but it worked out ok in the end.

TAP is a good, decent airline for international journeys. No complaints about the service, the crew, the comfort, or the baggage handling.

I like: The food provided was really good. I really enjoyed it Dislike: I couldn't open my window during the whole trip. Every time I wanted to do it, one of the crew came to me saying "please close it" It was a day flight. I wanted to have my window open and they didn't let me.
