I have two award tickets booked on aa for travel on 04/07/16. The connections are terrible being BNA-ORD 5:05 am ORD-PHL 9:15 PHL-BCN 6:55 pm. These are economy mile saver tickets. When I check availability there are several direct flights from BNA-PHL in economy anytime awards. Is it possible to change just this leg of the award from mile saver to anytime, and if so how do I go about it?
