Maybe OT... but I'm curious now.
This talk of tracking PAX and CIV scores of OWE leads me to wonder how they would track -- and value -- award spend.
For example, how do they view someone who flies 4-6 roundtrips trips per year -- perhaps 75K - 100K miles -- on CX metal using redemption's from another FF program. Maybe OWE that is using AA miles to fly F or J on CX. Or maybe a no-status flyer doing the same thing... using redemption's from a mix of AA, AL, AsiaMiles, etc.
There is a chance this sort of flyer might give CX more revenue than the GO flying longhaul Y, yet have no status. Do they truly fly under CX's radar? Low CIV?
