Do you have these tickets booked? Sometimes it is possible to call AA and upfare to a 1pt/mile fare (booking codes H, K, M, L, W, V) for an affordable difference. No harm in checking. Then you can do the Platinum challenge.
Otherwise do the gold challenge right now and the Platinum on/after June 16.
