I'm actually not too surprised AS is pulling the second ANC-ORD frequency. With AA back on that route with a 752, AS can probably put their code on the AS flight and redeploy that 73H to another route that needs it.

It made sense to have that route 2X daily in the summer when AA and UA both dropped it, but with AA and UA/CO back on it that 73H can probably make more money elsewhere, especially with the big push in Hawaii flying.
