I can never sleep on an airplane. I always want to but I never can. The seats weren't a problem, I'm just never really comfortable in a moving building. Do remember to get up and move around regularly, it can make a big difference in how you feel at the end of the flight. When you sit still for that long it can stiffen the most supple of athletes and can even be life threatening for us regular less-than-fit folks. When we flew over we went by way of Amsterdam and landed in Dublin. We had a Ryanair flight to Edinburgh that was pretty cheap but they made up for it with rediculous "overweight" charges. Those flights may work for commuters that are flying light. Plan those discount fares very carefully or you may end up paying more than you expect.
