Cons: "I sat in an emergency row with an empty seat to my left and really did not like how the passenger in the row behind me kept getting up and walking into my row to get his stuff from the bins."

Pros: "TAP always has great team members and crew. They are polite, professional and helpful. The flight itself is comfortable and relaxing; very enjoyable."
Cons: "TAP does not check your bags all the way through if you are having a layover. This makes NO SENSE and requires that you retrieve your luggage from baggage claim, and then check in once more and then another trip through security once again! This never happens in the US - one of the few things we get right. Also, I have never had to board a plan from the tarmac since 1970 in the US - why do we have to always wait for and take buses from our check in gate out to the flight line? And how is this ever considered, "Premium Boarding?" It's like a cattle car. Fix these things and I will sing the praises of TAP forever."

Pros: "clean and fast"
Cons: "use airport finger in Lisbon airport"

Cons: "We didn't select our meal option for vegetarian because the last time we did we ended up with a horrible, horrible, hockey puck like dry food option. We assumed there would be a cheese pasta option, as there usually is, well we were completely wrong. Both options were meat, even the salad had meat in it. So we got a roll with butter, a tiny fruit, and a disgusting wet dessert. Even the breakfast was meat and cheese. I got online to select our meal option for our return trip, and the options are out of control. We have a lacto-ovo-vegetarian option, whatever that is"

Pros: "Nothing"
Cons: "Everything"

Pros: "Surprised and delighted to be served a tasty sandwich and fruit drink plus glass of wine on a 3 pm 2 + hr flight from Lisbon to London"
Cons: "Seats uncomfortable"

Pros: "Clean modern aircraft"
Cons: "Left 35 minutes late; had to take a bus to the plane in Lisbon (no gate)"

Pros: "The fact that it was a direct flight."
Cons: "First of all, I would like to start by saying that I flight with TAP very often. I guess you can check on your system. I had good experiences in the past and actually recommeded to friends/family. I hope this flight was an exception. A few things were not that good this time. 1) First of all, the online check-in wasn't working until a few hours before the flight, and I didn't even give me the option to choose my seat. Once in the plane, I noticed plenty of empty seats in several areas of the plane. I could have had a much better seat. Also, the fact that the price of the luggage in the ticket is not included is insane! They let you know right at the boarding area. Another 100 plus dollars in addition to the 1,6000 that I paid for the ticket. Incredible!! And they only gave us 15 dollars voucher!! 2) There was a 2 hours delay due to a storm in the south of the USA. Although I am fully understandable with the fact that this situation is out of hands for the TAP company, is it in their hands the care and wellbeing of their passengers. As previoulsy stated, I received a 15 dollars voucher to use becasue of the delay. At any airport, for any decent meal, you will pay a minimum of 25-30 dollars. All items are more expensive. While waiting in the gate to board, we were not offered with snacks, water, etc.. additionally, no announements or updates at all. 3) I had a very uncofortable situation with one of the filght attenders. Male, very tall, dark hair and dark skin. When distributing dinner, I found the way he approached me very disrespectul, ironic and dismissive. ZERO customer services and he is actually the face of TAP in these planes. Unaceptable. I have to look all the way up to him, he wouldn't make an effort to band a bit (of course, not completely) to at least try to hear what I was saying. He was requesting me to speak loud but he would not make a minimum effort to get close to me. His demeanor and attitude made me feel very upsted... abuse of power... to the pooint that I ended up not taking the meal. No manners at all. He should understand that after hours of waiting (check-in usual time plus the 2 hours delay) we were all very tired. Particularly at that timeof the day. Some of us where up for since earlyi in the moring and you could tell that most of the passengers were exhausted. The second we got into our seat, we all used our blankets and try to sleep. He was not empathetic or councious about that. I felt very uncomfortable. Both of the girls that were also in the back area of the plane, were also lacking manners and customer services. I don't know.. other times was much better."

Pros: "Cabinstaff were friendly and professional"

Pros: "The crew did a great job."
Cons: "The boarding process was nutz. We had to take a bus away from the terminal to board the plane. The flight was delayed. I was not very happy to have to spend $92 to check 2 bags."

Cons: "TVs did not work, no sound/frozen on games"

Pros: "the food , drink and the crew"
Cons: "seats not very comfortable. plane full up"

Cons: "We booked flight several months ago and it included seating assignment, so we choose our seats. Then when we check-in they had changed them to the last row of the plane. We had received a couple of emails asking for us for option to pay for advance seating. Assume they had changed their policy and now were charging. We had a close connection at LHR and being last off, we almost missed connection. Horrible"

Pros: "Ice cream for snack."
Cons: "Flight from Oporto to Lisbon, when we landed they did not set up the ramp to exit the plane, I had requested mobility assistance. And the ramp was right next to the plane."

Cons: "The delay on the take off"

Pros: "Cabin staff was nice"
Cons: "Very cramped seating; rude baggage handlers; bad system for boarding"

Cons: "We had to postpone our first leg from London to Lisbon by a day and then they cancelled our return flight without telling us!!! So, we were trapped in Lisbon with no flight to return home. We called them and they said, "we cancelled your tickets and only have business class seats available for you and your toddler." We said no thank you. If we were going to spend 1k on a return flight, we were going to take British Airways. TAP, never again."

Cons: "The service was below average, nobody seems to be eager to assist. The food that was offered on the flight was below expectations. The company should work on improving customer care"

Cons: "No vegetarian option The last seats mean can't lean backwards when someone in front goes backwards :("

Pros: "Crew friendliness and attention"
Cons: "They ran out of diet coke and coke zero literally right after takeoff which is a joke!"

Pros: "I was very impressed with the Ground crew who met me off the plane and had already arranged for me to go on a later flight with Emirates. If it had been possible to let me know when I was on the first flight that my onward travel had been arranged then it would have been perfect."
Cons: "my TAP Portugal flight from Lisbon to Heathrow was so late I missed my connection to AbuDhabi."

The app didn't advise that the flight was boarding (unlike other apps such as BA). I missed my flight and they insisted on charging me more than what I paid for the entire ticket just to return home. I got back to London to find that my luggage didn't make the journey. Staff at Air Canada were unfriendly and unprofessional."

Cons: "Seats were narrow and sitting in aisle seat you were constantly hit every time cabin crew took trolley up / down aisle. Woke up by cabin crew banging into me."

Cons: "The crying children in front of me, the hour and a half delay, and the late dinner service. Dinner came at 8:30, after staring at those with special meals eat and finish an hour before everyone else, they should wait with the rest of us. Breakfast was pretty lackluster.
