Like others, I would have to say Singapore Airlines, when I went to Australia, it was about 30 years ago now but couldn't fault them. I particularly remember lovely stewardesses in traditional batik dresses and really nice food. I thought Virgin were very good the first time we took the children to America, lots of things for them, backpacks, colouring books, and boxes of fruit, biscuits and chocolate, although I remember our younger son smothering himself in the latter when he was about three. However, I do remember a real lack of leg room, we were of course in zoo class. I haven't liked any of the American airlines we have flown with, irritable stewardesses and they seem to run out of one of the two choices of meals quite quickly and then get very snappy when some people complained and most surprisingly, bearing in mind they were American airlines, we felt quite hungry on several occasions when we arrived at our destinations. We flew British Airways to the States last time, I thought they were competitively priced and their premium seats gave us more leg room than we remembered on other long haul flights.
