What you earn depends on the fare class and airline.

But when they're determining whether you get full or reduced miles, do they work on

a) The operating carrier
b) The codeshare flight number
c) The ticket stock.

For example:

A ticket bought on KLM ticket stock (074) for a Northwest operated flight but with a KLM flight number (e.g. KL6068).

Or:

A ticket bought on KLM ticket stock for a Northwest operated flight with a Northwest flight number (e.g. NW68).

Which, (if either), will get full mileage credit if the ticket is booked in 'V' class?


There must be an answer somewhere, but, like most things, FB don't make it clear!
