Since AA lets you make routing/date changes and upgrade from J to F for free on award bookings, would the following be possible?
Book CPT-DOH-PHL-LAX now as one award in J for 75k, upgrade to CPT-DOH-AUH-JFK/LHR-LAX in F as 2 awards?
What about the reverse: Book CPT-DOH-AUH-LAX as 2 awards now, then switch it to CPT-DOH-PHL-LAX as one award in J later?
