The positive YS Award Availability, reported by the [Awards/AS-MultiAlliance] Engine for that AS flight, appears to be 'phantom'.
Please use the [Awards/QF-OneWorld] & [Awards/DL-SkyTeam] Methods instead.
Thanks.
BTW this flight DOES show up as available on Alaska Air's website for 25K miles (where as the AA connections through MIA or DFW show up for 15K).
