Ok, I'm totally new to this guitar worry world....
It's almost 2009 and I'm going to Italy...... American Airlines and British Airways.   I have a Martin Dreadnaught and the old heavy duty, cushioned 5 latch case.    Of course, I want to keep it as close to me as possible, espcially since I will be playing the day following my arrival and don't want to worry about misplaced luggage.

Is it possible that I may be able to carry it on?
Has anyone tried most recently?
