Trying to book a FRA-MAN nonstop award ticket for April 19th. Lufthansa appears to be the only carrier with a nonstop (4X/day) - however, it appears that every coach seat on all the flights are sold out? Even on a revenue ticket kayak.com is only showing business seats (lufthansa.com is showing some econ seats for about the same price as business) Any ideas? surely, they aren't really sold out already?
