Uma antiga queixa minha era o tratamento dispensado pela tripulação da TAP aos passageiros. Muitas vezes faziam o seu serviço sem paciência e até mesmo de forma rude. Nos meus últimos 3 vôos pela TAP, a tripulação vem se mostrando muito mais cordial e até mesmo divertida, sendo bastante simpática. Ainda pode melhorar? Claro que sim, mas agora não tenho mais "medo" de pedir um copo d'água a mais para os comissários.

Sei que a tendência dos vôos low cost é não oferecer muito conforto aos passageiros, mas o espaço entre as cadeiras está ridículo até mesmo para pessoas com estatura mediana como eu (1,80 m). A poltrona, apesar de não reclinar, era até confortável, mas os meu joelhos ficaram espremidos pela poltrona da frente. Sem contar que, para um vôo de 3h, deveria ser disponibilizado algum entretenimento, mesmo que através do wifi (como já fazem as cias. brasileiras - se no Brasil já fazem, qualquer país do mundo é capaz de fazer!)

Next-day connecting flight after a delayed arrival and involuntary stopover in Porto due to air traffic over LIS. This time around, the flight took off an hour late because of [guess...] air traffic. Well, my dear LIS management, that's how you sink your national carrier.

It was fine, on time. I didn't have a checked bag or I would have waited in line at check-in for at least 30-45 minutes. Online check-in was relatively easy and digital boarding pass was convenient.

Seats are small, if you need to check a bag it will take forever. The underseat area is much.smaller than other airlines. The flight was very delayed because of some discrepancy regarding the number of passengers. Nothing seemed to be wrong but it took forever!

Keeping in mind it was an economy class, I thought the flight was fine. Decent food. I would have preferred some with a heavy cheese sauce. I had gotten sick in Egypt and I felt lousy (dizziness and headache). Despite my physical condition I thought the flight was okay. Crew were professional and airplane was clean. Beer to drink. Other than the fact I was sick, I enjoyed the flight.

The dinner option was okay. I felt the heavy cheese sauce pasta was a bit too rich. Other components to the dinner was fine.

Food was abundant and pretty good. I paid $91.95 US (think it was 75 euro) for the exit row and felt this was money well spent.

They charged me $90 for my luggage. Several weeks or perhaps even months after I booked, I received an e-mail saying I had booked Super Cheap Economy or some such. It had a link to pay for 'additional services' but not luggage. At the time of booking, I checked and the price given was $35. So, I have protested the additional $55 with my CC company and will see what happens. BTW the luggage was not overweight. They turned off all the lights, including my personal reading lamp, so I could not read and had to just sit there doing nothing. That really blew big chunks. I only got two small glasses of wine.
