Welcome to FT, groovyb! Except for AAnytime Awards, the inventory you are looking for is not publicly available, so your primary option, other than surfing AA.com, is to check out ExpertFlyer.com, which offers paid access to that hidden inventory. There is a free trial subscription if you want to test it out.

You should check out our wiki page on the different Award Ticket inventory codes so you know what to look for. This info is also available on ExpertFlyer.

Good luck!
