People seated in exit rows should have designated overhead space

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.

I wish to bring to your attention an incident involving a flight attendant that occurred on my recent journey. The attendant displayed a lack of courtesy, which was concerning. For instance, after accidentally spilling water on a passenger, the attendant dismissed the situation rather than offering a proper apology. Additionally, when I handed over my trash, the attendant reacted negatively because I placed a paper cup on the tray, she told me this doesn't go here and threw it back on my table. It was apparent that she was experiencing a challenging day, which unfortunately impacted the service provided to myself and other passengers. While I understand that everyone can have an off day, it is essential for customer-facing staff to seek support to manage personal stress without it affecting their professional responsibilities.

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

Two of three flight attendants were not super kind as I would expect. The very kind young lady in my section was wonderful but then lady and man up front were not. Sorry but it makes a difference !

I needed to add "Special Request" meal for myself and my trveling companion,and I ended up having to call their Customer Service. It took a while to get through but eventually I connected with a very proffessional and nice representative who took my request. In the middle of the conversation we were disconnected , as I was trying to all back, the TAP representative actually called me back and confirmed the special request for meals....he called me back from Portugal ! I was absolutely amazed,because that does not happen here in the USA. Perhaps some of the other airlines can learn from TAP's Customer Service. TAP's website at times can be difficult ,such as adding my TSA number. Ended up having it added at the TAP desk at the airport.

Great travel. Only issues were rude passengers, sorry to say.

There was no extra leg room as stated on the ticket and no foot rest. Do not pay extra for seats In Economy Plus, not worth the cost.

Crew and flight were excellent! THIS is how a crew and a pilot should act! They were nothing like our Rome to Lisbon flight! The few things that could be better? Organize the buses better and have better food choices. Also get bigger glasses for soda, water and juices. Other than that, this flight was excellent! John and Barb Sanford Plainville, CT USA

In Business Class, it would have been nice to be offered a beverage upon boarding. Food was very mediocre. Staff was friendly and courteous, but never seemed to go above and beyond.
