Little leg room in business. I am tall and could use more.

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils.

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.

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

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.

First, I was moved from my scheduled flight at 10:45 to 6:30. Bad form as I had a scheduled lesson in the morning that I couldn't get a refund for. Second, we were bused out to the plane and bused back to the terminal and sat and sat all with NO explanation until the end of the long wait. Third, once we boarded the plane, we again sat for at least an hour WITH NO EXPLANATORY ANNOUNCEMENT. Plane left and arrived 2 hours late. I missed a train connection adding hours to my trip home. Lastly, it's time the airport is upgraded or TAP gets priority for walk-on gates. As a 74 year old, carrying my carry on luggage up and down stairs between the terminal and the plane is a pain. Might be the last time I fly TAP.

Bused out to the plane, then back to the terminal. Plane was delayed for 2 hours - most of that time spent sitting in bus or plane with NO EXPLANATION of what was going on. Departure delay due to crew not showing up on time. FIX THAT. Why do your own international flights NOT have gates with ramps. Being 74 and having to carry my carry ons up and downstairs is awful.

Boarding the plane from 2 entries at the the same time front and back was ridiculous. I boarded from the back for row 7 and others boarded from the front for row 15, for example. We met mid-plane and had to squeeze past each other. Ridiculous

The flight was cancelled. the staff did not know how to arrange overnight, food and transportation accommodations required by law, causing long lines lasting several hours. the rebooked flight was then delayed 5 times from 9am to 4:45pm
