Hi ... so I'm about to book my first AA award ticket and had a few questions that I hope someone can help clarify. If I book an award (ie HND - SFO) and then later add a segment (SFO - JFK ) [same day so no stopover ... just an under 24hr layover] will there be a fee? We cant decide if we want to do one city or another just yet... With CX; if we wanted to book F but there isnt any right now, we can just book J and if/when F opens up we call AA to rebook and there won't be a fee but just more miles being taken correct? If we book F now but its not on the optimal day, if/when the day that would work better for us opens up can we change it w/o a fee? Could I do LAX <-> JFK/ORD <-> HKG ? Or is the MPM too high for that? Thanks!
