Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

Very borderline, low budget airline without low budget prices There are no counts of soda, everything is dispensed enlarged bottles and poured into tiny cups about 70 mL so in order to keep hydrated you have to take 3-4 cups at a time. Also, there was only one food item offered, pasta, they ran out of chicken right away. Snack was very poor. It was called tuna sandwich, which is truly borderline. The flight attend attendance seemed to be overworked and tired.

Plane was delayed, reading the gates on their screens was horrible. They posted it a half an hour before the plane boarded. By the time I got there with my premier boarding they have filled the plane because it was over booked. Gate closed at 12:03 I was there at 11:54 plane took over around 12:20. I was told they would put me on the next flight. I had to go to TAP information desk. They didn’t give me a voucher they just said they would put me on the next flight. At the desk I was told I had to punches a ticket. The woman said buy it online because it’s cheaper. It in fact was not cheaper. But I had gotten out of the long line that formed so I paid 200$ for a new ticket. At a later flight, not the next flight. I had checked my bag and was told it would be on my new flight. I was then bumped to an earlier flight and was told my bag would also be on my flight. After landing in Madrid loosing a day in my hotel i landed without my bag. They didn’t load it on any flight that day. It arrived in madrid the next day. Essentially ruining the first two days of my vacation. I’m now seeking compensation.

The business class seats were smaller and closer together than other airlines.

Didn't like much. Wheelchair assistance was almost nonexistent. No one at TAP check in process helpful. On the plane, stewards were not friendly and disorganized. Food was terrible for 8 hr flight. We were skipped at snack time and even though we tried to get attention using overhead call system no one even looked up at us to acknowledge. Being at the back of first section and by the lavatory we only were able to request when they came to pick up everyone else's garbage and they were nonchalant...no apology or even choice. The 1/2 half bread with slice of cheese was a waste. Deplaning was horrible but I'll blame lisbon airport for that. Plane left late at made good time still arrived about 15 behind schedule and for using remote deplaning and bus to terminal took another 20 min to gate. Those with connections were highly stressed. Took us 2 hrs from landing to get to ground transportation and exit airport. And that was with wheelchair assistance.

Great price for really nice seats and the plane and staff were great, only 5-10 minute delays!

Tap was very frustrating in Lisbon. Not enough direction and help. Mixed messages of where we needed to go. Seats were not very comfortable.

Everything went as expected. Luggage arrived at my same destination and nothing disturbed my vacation.
