NO HELP FINDING PROPER CHECK-IN LINE; STAFF PERSON WE FOUND WITHIUT ANY SIGN WAS ACCOMADATING

Seating too tight, no way to reclining No USB outlets

They ran out of food and on the flight back to NY there was no wifi nor any socket to connect your plug to charge your phone. Also the crew was not friendly as they did not want to throw out my empty water bottle after she told me to hold on to it and then said no.

Boarding slow and chaotic. Food was terrible. Flight attendants were nice. Sears were comfortable.

food was terrible on the plane, bring your own food, its not worth eating.

I feel like the boarding process could be a little better. But the staff and everyone does a really great job.

Flight was good. Would be great if we had free WiFi

Flight was late, and not sure why. The business class lounge in Porto is not proprietary to TAP, and is really substandard, almost as bad as "The Lounge" in Boston. It was a D, which is better than the F experience in Bostonm where we left "The Lounge" for a better experience in the terminal. It had better food (an extremely low bar), ok beverages, and wasn't as crowded as the Boston one, but no restrooms. To use one, you had to leave and go downstairs. There's no down escalator, and the elevator might be able to crowd 4 people. Otherwise, you're carying your bags down the stairs. I hope the Lisbon club is better, but for TAP to provide this in the 2nd largest city in the home country is disappointing. They put out an announcement to proceed immediately to the gate, but there was no plane and few seats. from the lounge, 8 people with bags waited in line for the single tiny elevator. After almost an hour of standing, we finally boarded. TAP, at least on this plane, doesn't offer a welcome drink to business class passengers. Having said that, the crew was very friendly and accomodating. We landed about an hour late and then were told we were going to be on the runway for at least a half hour because no gate was available. So, bottom line, D- for pre boarding, A for flight attendents, B + for business class food, and Incomplete for post landing.

Special meal AVML was terrible Move selections were mediocre No Wi-Fi offered

On time. Good meal. Overhead cabin lights inop in entire cabin. Seat recliner did not work.

For my first experience flying, I was blown away with the service, the flights and staff

We boarded late; there was a problem with passengers that I believe TAAG could have handled much better. The Crew Handled it Excellentely but TAAG was not able to resolve the issues instantly and led to a 2 hour delay

The scheduled departure was delayed 9 1/2 hours and then delayed another 45 minutes due to baggage or something. Apparently the return flight is delayed 10 hours also, which means I miss my Lufthansa flight out of Luanda. Perhaps this is a scheduling change for which people were not notified until the last minute.

I did not receive any confirmation email of this booking and only on receiving it 24 hrs closer to the flight - I tried to cancel it as I has already booked another flight

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