Getting hold price
I'm not sure if this still works with today's coding, but in the past I was told to note my record # and log out of AA.com. Then pull up the reservation and you can purchase it at the hold price. I know web services knew of the problem some time ago, but I don't know what, if anything, they have done about it. But remember to NOT LOG IN and the ITN will not be repriced.
Good luck.
