Can anyone tell me what the earning percentage (e.g. 100% flown Kilometers, 50%, etc...) is on BA (BA & IB Metal) and QF (QF, AY & LA metal) flight numbers when booked in M class in Lan Pass?
Thanks.

I tried to have information from LAN Chile's web pages without results.
Here's however information from Finnair's page (they might be the same for LAN Chile). I don't think that there's any differences on who's metal you're flying, what matters is your flight number as shown in your booking.

BA flight code: M class 50% of kilometers
IB flight code: M class 100% of kilometers
QF flight code: M class 100% of kilometers
AY flight code (on international): M class 100% of kilometers
AY flight code (on domestic): M class 50% of kilometers
LA flight code: M class 100% of kilometers

For example if flying between Helsinki and Bangkok, I noticed that for L-class AY only offers 50% of kilometers whereas QF offers 100%. This means that for a oneworld explorer ticket it would be better to book the HEL-BKK on the Qantas flight number (if they have availability in L-class).

What frequent flyer program are you in ?
Can make a difference
