Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

One of my checked luggage was damaged. Cracked on the top by the handle.

Not so good. Crew was not as attentive as they should have been especially if flying business class. Only offered dinner 2 hours after takeoff. My flight attendant seemed overwhelmed. Pushed my help button but no one came. I explained everything on my previous review.

I have been flying united for a long time but now I’m done

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.

Flight was over two hours late, but they notified us early in the morning. They ended up changing planes the food on board that was extremely mediocre and we were in premier class.

Food was very bad Crew was not so welcoming. Chairs was so uncomfortable

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

Boarding felt a little chaotic as everyone was waiting around the gate. Food was great, service was good.

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.

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.

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

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

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

We had seats 1 D and 1E which is right to the front as there were no other seats available. It is right up at the galley and toilet. Whole flight was very noisy and busy and we didnt get a good flight or rest the entire flight. Its was a pretty costly Business class fare that felt like Economy class experience.

They took 8 hours and eventually cancelled the flight. Compensation has been very lackluster and communication has been slow and terrible.

Airline attendant never walks along the isle to check if everyone is ok. The food is worst I’ve experienced. Chicken pasta is very salty while the fish is bland and over-cooked. Only two toilets for the entire economy section.
