If you follow the "fare rules" link below the price calculation there will typically be a lot of remarks about First and it will be pretty obvious it's not a coach / economy fare.

I believe AA now only has one domestic aricraft type (767-200) with a 3-class layout, so be careful of anything where the equipment is 762. Finally, also be careful of any short international flights to Mexico, Canada etc. because a lot of these are sold as Business not First and get less TP's.
