Yes. That is Last Flight In First Flight Out. Ditto on AA award (both domestic and international) but AA's must call in to book as online booking would not offer up such option.
However I have seen the LIFO on a pure domestic route involving AS and AA - being offered as one of the route options on AS booking site.
