from airfrance.us:

(3) Partner flights operated using an aircraft owned by another airline are not eligible.

Concerning earning miles on Skyteam flights, the following booking
classes do *not* earn miles for Frequent Plus members

Aeromexico : C D E G P Y U
Air France : G B N (only domestic flights)
Alitalia : D U
Czech Airline : H E I Z
Delta : E N O R S
Korean Air : A D G U N B Q

D & Z fares are usually discounted C fares.


I do not know what CO,KL, & NW fares are not allowed.

Since I fly D & Z fares almost exclusively, and fly the VS metal codeshare on CO to LHR, it looks like Frequency plus is not the program for me. Back to the drawing board.

Will call OK, and find out if they have any such rules.
