It was difficult to tell if the checked luggage was included. London Heathrow is huge and if the second flight hasn't been delayed I would have missed it.

Great baggage policy in BA.. The worst part was experience at London Heathrow airport. Security was slow, too many people. Almost lost connecting flight even with 2 hours layover.

I would suggest calling the airline to make sure that their TV screens work on the back of the seats, and if they don’t work that the entertainment option would work on your cell phones.
