There was not even a single time where united airlines from lga has made to the gate straight , 1 hr if delay today

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

I had a good time. However, I paid for the wifi and it was in and out the whole flight.

3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.

Everything except the food and entertainment. It was a great experience though

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Flight was delayed from 35 minute delayed aircraft arrival to 90 minute delay causing us to miss international connecting flight on SWISS resulting in 16 hour delay to reach detonation causing significant angst, monetary loss and discomfort. SWISS transfer desk and staff was like robots not willing to help at all.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

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.

Boarding was slow and getting off the plane took a long time. The crew did not have enough water for the trip.

Boarding was a bit chaotic, planes were on the oldish side. Otherwise, very nice flight. Would fly them again.

The flight took off two hours late. What was good was that I was getting an information on this earlier in the day. The lounge agent sent the passengers to the gate way too early. That was annoying. The food aboard was disgusting. The service aboard was okay. The seats were good. Overall, it's a very mediocre experience. Well, it's not a five-star airline and not one that aspires to be one. Comparing TAP Portugal to Iberia or Lufthansa, I'd rather see it as a three-star airline, even though it's website works much better than what Lufthansa has been trying to pull off for the past decade.

Flight attendants in business class were rather indifferent While in second leg operated by Portugalia TAP subsidiary were outstanfy

Horrible experience at tbe check in ladie she was very racist ,she doesn't speak portuguese too and forced me to check in my carrion bag and I saw everyone with carrion bag inside anda lot of space ,she was rude unprofessional

An old airplane with very uncomfortable seats in the Comfort “class! Small, narrow, and hard seat. Entertainment options are inferior, old movies. Boarding started at the back of the airplane, as we entered the aircraft last instead of after business class, risking the possibility that the comfort section would not have room for carry-on in the overhead bin. The food was ok. White wine was terrible. Overall, the flight felt worse than cheap airliners, and the price was as high as premium carriers.

The long wait at JFK made the trip horrible. Also not having enough buses when we deplaned was annoying

Great overall experience with TAP - would not hesitate to recommend for your next trip to or from Portugal

What didnt i like? You had to pay for seats after the booking was paid for. If i knew that beforehand i would have booked with emirates for a few dollars more
