Hey Javichu,
Are you considering going from AMF directly to the majors, or is your plan to go from AMF to a regional and then to a major? A lot has been written on how well the AMF-step in this scenario works out. The number of AMF pilots who have gone directly to the majors is quite small. Yes, a move from AMF (or a Caravan) to a regional would be a cut in pay, but this seems to be the best and most common way to get to the majors.
