Was online to Aeroplan to request credits for flight YYZ-HKG in Oct and return NRT-YYZ in Dec. (Forgot to include Aeroplan # on locator).

Flight YYZ-HKG accepted without problem. Aeroplan would not process NRT-YYZ leg because "This flight request cannot be processed online as it is a non dcs origin. "

Why should it matter whether the flight is a domestic or non-domestic origin? Don't you just love AC IT!
