Lounge poor. Food poor. Airline service just ok. Business class seat not comfortable.

Business class seats were harder than expected, and lie flat we're not very comfortable. Less expensive than other business class flights, and much better than flying economy. The crew was excellent, as was the food.

This was one of the worst flights I have ever taken in my entire life. First of all, I traveled Economy, but the seats were TINY and cramped. Not just for me; everyone around me was complaining of the same thing and said they could not get comfortable. Then there was the issue of the heat. For whatever reason the heat on the plane must have been turned to FULL BLAST, because even at 30,000 feet, it was SWEALTERING. Everyone was drench in sweat. Then, they were SO STINGY with the amount of drink they would give you. If you asked for water, it was in a tiny, paper cup (think bathroom cup) and they only filled it 3/4s of the way as if the cost came right out of the pockets of the air stewards. Everything was a money grab, you could tell! You had to pay for the WiFi, which was garbage slow, and the onboard entertainment was limited and stale. If I EVER fly TAP again, it will not be Economy class. What a disaster!

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

The crew was excellent. What I did not enjoy was the food. I have taken many international flights and this was on the low end. Otherwise the trip was fine.

Seats were the most uncomfortable seats i ever experienced on a flight to Europe from Boston. It was a waist of money in buying premium seats for top dollars. I want my money back for what i paid extra for my seats. Awful conditions!

The flight crew were absolute rock stars. When they came to the gate they looked like royalty, so chic. They also were extremely kind. Food was good and I loved the lack of plastic waste. The flight was lovely and smooth.

We were unable to check in due to technical problems on TAP’s end. The flight was delayed forty minutes with no reason given. We received timely notice of the flight delay. We were also notified of a gate change. The new gate was at a different terminal. When we got to the new terminal, we learned that we had to go back to the old terminal first to check in. This information should have been included along with the gate change notification. Also unexplained, the steward skipped us when offering breakfast.

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.
