We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

From the first moment you interact with United Airlines, you can expect nothing less but extreme frustration. The baggage handler at the bag drop seems completely unbothered by the presence of customers waiting in line. No help was extended to load the baggage whatsoever. And if any of your bags is overweight by 0.01 pound they will make you re-distribute everything in your suitcase just to play power trip. When it was time to board no help was extended to customers to locate their seats. Moreover. It was a chaotic mess at the gate when it was unclear who should board first and everyone just bunched up, trying to get on the plane. I am sure the crew was doing their best to perform their jobs while being paid their wages however it shouldn’t be that hard to smile once or twice when you’re in the business if serving customers. It is a shame for the United States of America to have a flagship carrier of such low caliber. Our flight was also delayed by about an hour and a half due to further delays prior to our inbound flight. Being someone who has travelled for both business and leisure in Asia, Europe, and South America I have never experienced such poor quality of service.

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The best airline I have ever travel , really good customer service, attention and service !!

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

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.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.

I had a business class ticket from EWR to Madrid with a layover at LIS for 11 hours. It was obvious that I needed to pick up my luggage in Lisbon for 11 hours and check it in again when boarding the second flight to Madrid. Before buying the ticket, I called TAP customer service. Customer service assured me that I could get my luggage in Lisbon. When I arrived at Newark airport, I immediately asked to check my luggage to Lisbon. However, the TAP employee refused me, saying that I should resolve this issue upon arrival in Lisbon. She checked my luggage to Madrid. I asked the TAP employee at the gate to help me when boarding the plane, I asked the flight attendants manager on board the plane to help me. All the employees refused to help me and said that I should resolve this issue in Lisbon. It took me 4 hours to resolve this issue in Lisbon. I arrived at 11am and they didn't give me my luggage until 3pm. As a result, I was so tired after a sleepless night on the plane and 4 hours on my feet at the airport and all my plans were ruined that I couldn't fly to Madrid. It was a terrible experiance,

The seats were not designed to comfortably see people in coach for more than 10 minutes

A good, comfortable flight with friendly crew and good entertainment options.

Very rude person at the boarding desk; flight attendant coughing 3 inches from my face three times- not even covering her mouth; boarding process very unacceptable for older people with stairs to all planes (are you all stuck in the 1960’s?). I am sure that I am not remembering all of the negative things, but I am sure you get the message!

There was chaos at the Naples airport. We arrived three hours early for the flight but there was no invitation available about where to go to check bags until an hour later. Then we had to go to a different terminal to check our bags and check in and back to the first to board.

We flew TAP last October from Newark to Lisbon. The meal was bad. This flight had good food. Also, this flight was delayed. There were TAP employees waiting at Lisbon to make sure we made our connecting flight. I find the TAP website and app frustrating, but the service once we reached the airport was very good

The airport temperature at the airport and on the flight was too warm

Boarding too way too long. Biggest peeve: zero in-seat power in economy! No plug sockets, no USB ports. Plane was an A330, so not old.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?

Enjoyable flight, helpful crew everything was organized to accommodate passengers.

The on flight entertainment system touch screen system and the USB charger did not work on multiple seats on least 4 seats an in different rows. The attendant tried to reset the system but was un successful. I couldn't change my phone to get my ticket for my next flight. This was an international flight I changed seats and the problem was the same. the flight attendant offered his power bank

I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.

The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?

This was the second time on BA, food terrible, bathrooms gross,( granted, that was mostly due to the disgusting children urinating all over it)boarding was late and disorganized. No gate issued until last minute st Heathrow, bad system, caused undue stress. Seats were painful, that's what you get for traveling like a poor in economy, right BA? Should have been able to afford business or first class if you want to actually be able to walk upright without back pain after a trip.

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

The delay was not communicated via text and the person who helped with check in also didn’t inform me about the delay. I ended up missing my connection and it was a waste of 5 hours. The crew didn’t mention there would be someone at the gate informing of if I would be rebooked and there was no signage. Overall a very poor experience. The British Airways app was also very buggy, and didn’t work. I will avoid flying with British Airways when possible.
