The plane was dirty the food was awful and the boarding process took too long

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

The business class seating arrangement for LHR to MAA was very uncomfortable. The movie options were terrible.

Ohooo it's fantastic 👏 I love it 😀 😍 ❤️ it's on time ⏲️

Very bad. Business class money is paid but service is worst than economy with empty middle seat. Very low grade food, very poor toilet. This should be highlighted as worst business class in the world. Government of Jordan should ban British airways for misleading information.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Even in business class, no 2 members of our family including kids were able to sit together. I booked the tickets months in advance. The all my luggage was left in London and arrived 2 days later. It took hours to report the missing luggage at the airport and 3-4 hours to recover one of the bags from the airport with mind bending amount of paperwork. Worst experience ever, I would seriously reconsider traveling by British Airways again.

Crew attentiveness and service as well as the quality of on board dining could be better. Seats and controls are very dated.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.
