The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

The chicken was so dry it was impossible to eat. No substitute was offered. The port to charge my phone was broken and all I got was a shrug from the crew. The entertainment system was glitchy and subtitles didn’t load. Crew seemed fully uninterested and unfriendly.

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.

They left our luggage uncovered on tarmac in pouring rain during an hour delay of departure! At our final destination, we found ALL OF OUR CLOTHES/SHOES soaked all the way through!! Our 1st connection plane was a great business class accommodation but only 50 minutes long. Our 2nd connection from Lisbon (another delay with luggage uncovered on tarmac) had only the extra legroom and mediocre food in business class - no entertainment and no extra comfort seating. Will not use TAP Air Portugal again!

The food left a lot to be desired. The crew was great

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

Departed late. Flight crew some of the most professional I have ever experienced. First time we’ve flown this airline

No difference between business class and normal same seat everything same, waste of money

They allowed me to book the flight, which took quite an effort to find the best option for us, and then 2 months later, cancelled it because they didn't think 90 minutes was enough time to get between connections. Why let me book the flight in the first place? I am somewhat disappointed in Kayak and will be choosing other options in the future

Absolutely unacceptable level of service for a Business class: lousy drink and food options, disgusting food (inedible meat, watery rice, etc...), pathetic level of attentiveness from staff, Business class restrooms were not accessible for long periods because blocked of by staff...overall extremely disappointing, will NEVER fly Business on TAP again.

Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.

The whole experience was excellent, O can say out from Miami the best airline to travel with for any European destination. Since the ground staff to the inflight crew attention was great, service on board 10 of 10. Finally the 380 is very confortable and nice to travel.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

1st class seats NOT REALLY 1st class or business class but like premier economy. Should be listed as such or named something else. I have flown 1st class with other airlines and they are nothing like it at all.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

Worst airline in the world. They downgraded me from business class to economy with no compensation.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.

Overall ok. Best part has always been the sundae dessert.

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

Even if you wait for connecting passengers you should not be an hour late departing waiting their luggage. Your passengers may have connections in the other end and you harm them.
