Fwiw whatever AA did which reduced my available credit by the amount of my reservation when I called to ticket for the reservation that they then repriced and has not yet been ticketed... Has been in place for well over 100 hours so the 72-96 hour time frame seems typical not strict.
The one that ticketed did behave largely as you said. Two charges have come on and the available credit has not further reduced so the pending charge has presumably been removed.
