A couple of years I flew Lufthansa's new A346, and was very disappointed with the legroom in the economy cabin. The seats were much worse than the old leather one on the A300 that are used for short hops.
I know that airlines must make a profit, but I don't think squeezing more people into economy, especially on long-haul flight is the way to go.

P.S. The cabins are not from Lufhansa A346 & A300, but I think the seats are the same.
