Food on the return journey was not food that a European passenger would find acceptable. I was glad of a box of fruit and a kitkat that I took on board. With a long flight over time zones you need to eat something.

BA had too much reliance on self-check-in machines and not enough staff at desks. For a large family traveling it is more time consuming and can be difficult.
