You should get 20 points for each of the domestic legs, and then 120 points for each of the long-haul legs - so I reckon 520. If you don't already have your four BA-metal legs, then stand by to lose some tier points.
Does anyone know if the BA legs above (EDI-LHR//LHR-EDI) would count for this, as I assume they're booked on the CX ticket?
EDIT -

What's that, 3-2 to me now
G-BOAC?
