The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

It was excellent service in the snow storm gives us hotel and transportation. It will be more better if u can add one more meal because it’s a long flight boring journey. If you give extra meal time passes faster and can enjoy the trip better

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

No entertainment except on app. No outlets working to charge. Good service

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

On this flight...fine. The one from India to Abu Dahbi, awful.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

Very disappointing #1 - You have to pay extra to use the business lounge, or else you sit in the cold airport for 7 hours and fall sick #2 - Did an awful job with boarding, they turned on the "last call" notice on the monitor made the passengers come running to the gate, once the passengers came close the crew would tell them - hey we are not boarding yet, this included passengers with children also, this was happening all the time, it was pitiful to see #3 - Did not have the courtesy for the passengers in the business class, there is a reasons why people choose business class, because they need to get to work, that means sleep is very important for them, in the business class, the crew members would themselves cause so much noise by closing the door in a loud way, once the crew member does it then the other passengers are also doing it, #4 - the food did not smell good, #5 - The Abu Dhabi airport is small, so not a whole lot to do, especially when the layover is 7+ hours. #6 - Did not provide the slippers with pajamas, #7 - also the pajamas also I had to ask, only after asking it was provided. #8- Asked for an extra pillow because the pillow they provided was not tall enough, the crew member said there was no additional pillow and gave me something like a blanket, I tried my best to use that as a pillow, but my head kept on sliding and that messed up my sleep and did not get deep thorough sleep Overall the airlines did not have an understanding of how to care for the passengers, especially the business class ones. Overall it was a bad experience, I would much rather spend the money with Qatar airways, the experience with Qatar is so much better.

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

I paid for a very expensive Business Class seat to and from Cairo Egypt from Charleston SC. There was partnership from states to London using American Airlines. That leg was amazing. The British Airlines leg was a joke. They used the standard no leg room 3 by 3 seats. A tray was put on the middle seat. The trip was 5 hours, from London to Cairo, thus my BC purchase. There was no screen proving tv/movie options, only a small device plug. The fold down tray and the bag of peanuts were typical of normal short run flying. The one toilet was located in the galley. We all got to know each other well. This was my first and last trip with British Airlines. I now understand why they would NEVER give me a seat chart so that I could make a selection.prior to departure. It honestly would not have made a difference, there were less than 50% of occupied seats. Apparently everyone got the memo but me. I have never felt so cheated as with that trip, got to so another going back to London, yeah. I will be sending a letter to customer service and asking for a refund. I will be photos comparing the two BC legs. OH, one more thing. The FC ticket holders got bulkhead and exit row seats. I know they had to be thrilled

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort
