FF#s on PNRs
 

I assume this is possible but wanted to make sure:

If two people are booked on the same PNR/reloc (eg DONE4) can each have a FF# of a different OW airline on that one PNR (eg I QFF Mrs alect AAdv)?

On AA's system, SABRE, you may segment select and do whatever you want to credit which segment to which programme.

On other airlines, ie BA's, I'm not too sure.

So it depends on WHO issued your ticket to be able to do what you want.

Amadeus allows separate FF#-s per each passenger and/or flight segment
