if you can get 2 first tickets on aa for the days you want right now you could buy 14k miles with 3k bonus for the account with 96k in it, this will cost $385 then book 2 tickets one way suing account 1 and one return using account 1, the book on return on account #2. while i realize it is not a good value to purchase miles, spending 385 to lock in first class tickets to maui can some times be really worth it,
remember there is great value in going on a great vacation, much more than saving 20k on a ticket you woudl never have bought in the first place.
