You can try to cite http://www.asiamiles.com/am/en/site/...DropDownList#6, which states, "If a member's air travel is disrupted due to reasons beyond the control of CPA or an airline partner (for example, extreme weather conditions/acts of God) and the member is forced to change carrier, mileage credits on the disrupted segments of the purchased ticket will only be credited to the original itinerary. In such circumstances the member will need to mail or fax the original passenger receipt and boarding pass to AML." You can double-dip and get miles from UA partner (such as A3) also.
