From the rule sheet at http://www.oneworld.com/documents/10...9-d346ec820edf

Reservations Made 29 or more days before departure : Complete Ticketing 25 days before departure
Reservations Made 28 - 8 days before departure : Complete Ticketing 3 days after reservations or 7 days before to departure, whichever comes first
Reservations Made 7 days or less before departure : Complete Ticketing 24 Hours after booking, but no later than one hour before departure.

AA itself may have a policy requiring tickets to be issued within 3 days where it issues them, but this isn't a ticket rule
