Mr Angry, EK does recommend sleep/rest patterns for all ULR pairings, although they are apparently produced by people who have only ever done one from the comfort of a first class suite and therefore didn't find it the least bit tiring.
They also probably never envisaged rest having to be taken in a glorified Dog Kennel surrounded by screaming infants and 8 year olds thumping on the walls.
Fatty, the 380 fellas I know are horrified at the prospect of a 24hr layover in IAH and none of those are commuters. Fortunately on the tractor there were/are enough septics who want their fill of homeless people to take any US trips that turn up on my roster.
