Thanks Mutt, I'll have a look.
I think this is the perfect aviation topic where the answeer is, "Well, it depends". Came up the other night flying in LRC at FL360 with over 90 knots on the nose. Slowing down into that wind can't save money.
Big Boeing FMC Guide suggests that ECON will save more gas than LRC.
