The food was delicious and the meals spaced reasonably. The movie selection was very extensive. The crew was readily available for most issues that cropped up.

An elderly disabled passenger was allowed to seat in closed off seating and store her canes under her seat causing them to jut out into the aisle. As she required a wheelchair to get on and off the plane they should have reseated her somewhere with more leg room and easier access to the restrooms

Food and entertainment was good.

Most of the flight attendants were nice. However, on one flight a couple of them were rude. One made a comment "you are making their job hard". I was sitting across the aisle from my mother who is 80 years old and was getting her entertainment set up since she is technically challenged. I told him that I didn't mean to make his job hard. After that, he then smiled regularly to make up for the comment. Also, one of the flights we had to buy coffee, water, or anything other non-alcohol beverage we wanted to drink. Not sure why on one flight we didn't get free beverage service when all of the other BA flights provided it.

The flight crew from the mel to lax route were excellent. One was especially attentive to my 2 toddlers and gave me a bit of a break, something that has NEVER happened in over 40 flights traveling with children.

I think something was broken in our section (mel to lax) as it was uncomfortably hot and the flight crew tried to get it cooler but could not. I’ve never experienced a flight that was too hot, usually the opposite. It was stifling.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!
