On-time flight. Nothing out of the ordinary. The food offering upfront could be better.

I thought Miami's airport was very disorganized during the Boarding.

Very efficient boarding - other airlines could learn from them. Friendly, efficient crew. Red eye flight, so dinner meal was irrelevant. Breakfast could have been more substantial. Seats reasonably comfy.

I have been flying internationally for most of like. My first trip with TAP- wonderful! I look forward to flying with them more frequently in the future!

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.

Perfect although it took an hour to board the plane but other than that it was great

The quality of the aircraft and the professionalism of TAP's staff were perfect. The quality of vegan meals can be hit or miss depending on the airline and the city of departure; on this flight, our vegan meals were quite good. The boarding process for the connecting flight in Lisbon could have been organized a bit better, but it did not spoil our overall experience with TAP, which was excellent. I'd definitely recommend TAP to others.

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

We liked the crew. They were competent, professional and friendly. The only big negative was our departure was delayed several times and the airport staff did not communicate what the problems were and what we should expect.

Great staff who were ready working with smile 6 in the morning on New Year’s Day. Although security checkpoint was way too busy, the airline staff were understanding and waited few minutes after boarding. We took off not only exactly on time, but arrived 20 minutes early. Two thumbs up!!!
