The food could have been better. And the chicken sandwich was not nice at all.

Not the quality I was expecting from a company that has been around for ages and charges high prices

The whole experience was very disappointing. Drinks could have been served and offered more frequently. The seats were reasonable but considering I paid for premium economy, I felt cheated. I flew premium economy with Japanese Airlines ANA 5 years ago and their service was by far, superior. We had access to the club lounge, better seats and excellent service. Out of 10, I would rate the experience as 4. Everything felt cheap and the Airbus aircraft are far better and more comfortable

Hand bag was taken to be checked in at boarding gate

Flight was okay however bags were left in London even though we had a 7 hour layover. Bags are yet to be confirmed to reach final destination. Horrible work.

Quiet and comfortable aircraft, pretty smooth flight. Very comfortable business class cabin with decent entertainment. Good service from the crew. All in all a good experience.

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

When i booked my flight, my ticket shows that i have 2 pieces of luggage allowance. Once i got into the check in, i was informed that i needed to pay extra for my two suitcases, and was put into a very precarious situation, I had to pay close to £200 for my two suitcases and these were not extra burgages, I felt extremely disappointed. In case i never had the kind of money, it meant that i would have missed my flight

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.
