This flight was my first one with British Airways - it absolutely fulfilled my expectations and I'll prefer to take BA instead of LH for the next trip to London.
The aircraft looked in a great shape, the seats were quite comfy for this short flight and the crew was friendly.
Taking the BA 767 is definitely the most uncommon and maybe the best way to get to London.
