Hello:

I am stuck with the following problem. Taking advantage of the AZ error fare currently running wild on another forum, I am trying to input my AF FB# into AZ's MMB.
MMB offers a list of airlines whose FF programs are affiliated with AZ but not AF per se. Indeed, the closest (syntactically speaking) FF program to AF is listed as "Airline. AF": if I opt for this option, I can enter my AF FB# but receive an error message (invalid data entered).
OTOH, if I choose KLM and enter my FB# (same as AF's), all is well and the changes can be saved.
Thus I have 3 questions:
- As AF and KLM share the same FF program, does it make any difference if I choose KLM instead of AF in MMB as the FB# is the same?
- And, as a way to enlighten me, is FB run separately by both companies?
- Is it possible to transfer my miles balance run by FB/AF to FB/KLM? If so, How?
Any input gratefully received.
