Although I haven't flown by 757, the 767 & 777 services from the UK are good and I'm sure the 757 isn't too bad. My wife flew the 757 service this Christmas, apparently there's not an entertainment screen / radio per seat, just a TV at various points down the aisle. In any case, it's going to be a good deal greater than in a DC10 with NW (awful). To add to RNE's midwestern sensibilities, London really is fantastic in summer. ^
