A very good flight. They were not as accommodating in relation to the food and beverage options. Last year on the same flight to London, they offered an additional glass of wine beer or vodka. They also offered extra snacks and were constantly checking on us. This flight, they barely acknowledged our presence. They were not rude just not sociable or readily accessible.
