[Mickaboo Action] birds on American Airlines?

I just checked American Airlines website and they now state that they will only transport dogs and cats. Does anyone know if that is a new restriction? Have anyone run into it before? Other than Southwest (which transports NO animals), everyone else (United, Continental, Northwest, Delta) says they transport birds. Michelle www.Mickaboo.org Mickaboo Companion Bird Rescue P.O.
