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.

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.

Very pleasant flight, crew was very nice. The flight was really smooth, big plane. The seats are kind of close together, so comfort was just OK. The boarding process on the way back to New York was a little chaotic. It took a long time.There were no announcements, no loudspeaker just one staff yelling out of instructions and a lot of people crowding in before their term to board. So that could really be improved a lot.

The crew was very nice. The food was good. The entertainment on the way back to Miami wasn’t as good as the flight over. I wanted to watch Wicked but on the way over from Miami to Lisbon but the screen didn’t work. On the way from Lisbon to Miami Wicked wasn’t an option. Liked the option to check out overhead carry on with our checked luggage Overall the flights were very good. I would fly TaP again

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.

Worst: long walk to baggage claim Best: left on time

Got in on time. Food was the worst ever. Comfort was terrible. Check in was incredibly bad.

The flight schedules are better than some airlines. Their website is terrible, it doesn’t store any information so every time you fly you have to re-enter the data. The flight was late taking off but we still got to our destination on time.

Flight delayed by >1 hour. Long boarding involving riding a shuttle to the plane.

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.

Short lay-overs and total flight times. Everything else could have been better.
