it was a very short flight so my expectations were low.

Entertainment kept turning itself off. Gave up on watching a movie.

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

The flight crew where really good. Better then the crew from BNE to SFO

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

left on time, reasonable boarding process arrived early luggage came out quickly

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

Pushed back only to get deplaned due to a tire damaged by ground crew. They did at least go pretty fast. The bathrooms should be banned under the Geneva convention. No room to even sit straight on the toilet. The under-seat entertainment units block what little leg room there is.

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

First time flying Business with Tap, I think it was a very good experience. It beats many domestic US carriers, the food options were really great, authentic Portuguese food, wines & deserts. Next time will do the free 24-48 hour stopover in Lisbon or Porto for sure.

We upgraded to business class. Nice seat with lots of room but otherwise not impressive.

Delayed departure Madrid to Lisboa and my luggage no arrived

this flight was awful from pre-boarding to on the plane. There needs to be more coordination between TAP and My Way. We were in first class and I am handicapped. BY the time we got on the plane there was no place for our baggage and the crew did not handle the situation well. They gave us an argument and said that we'd have to have it checked. Then, after I complained they moved some people's bags to put our small carry ons several seats back of our seats which were in Row 4.

Late. Lack of updates. Rude hostesses. Terrible food. Lack of headphones.

Flight was delayed but crew gave little to no communication, then “began boarding” but really just had everyone stand up and wait for an hour without any news or updates, as if we were going to start boarding at any second. Total chaos. Seemed like this was their first time boarding a plane. When we arrived at our destination, we waited for over an hour for the baggage claim belt to even turn on. Probably waited at baggage claim for our luggage for close to two hours. Everyone was very confused and of course we all worried that the luggage was lost. Again, zero communication and everyone we asked just said “I don’t know.” So we were left wondering whether to wait, or file a missing baggage claim, or check the other baggage claim belts (which we did every fifteen-twenty minutes because we were just confused). Lack of communication throughout the experience was a huge issue.

The value is there, but the layovers in Lisbon were not great. The passport control was so bad that a 2 hour layover became very tight and on the return the Terminal was barebones which made it a long 3 hours.

From Casablanca to Lisbon our baggage 2 pound over they want me to pay $120 for 2 pound which unexpected we are two family 8 of us they counters lady her customer service is not good I fly frequently for my business next time fly with TAP Air I will think twice

Booked business with TAP from LAX to Cabo Verde - overall ok, but just doesn’t feel like business class. More of a budget airline

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.
