Thanks for the quick replies.

I have always worked on the presumption (clearly wrong from your comments) that the eligibility for mileage accrual (and amount accrued) of a particular booking class on a particular carrier will be common to all FFPs. Is there some relationship, or does one have to check an individual FFP as to the mileage accrual for a particular flight? If so do you know if there is a handy way to look up this info for all *A booking classes/carriers/FFPs? (And if not, if someone with too much time on their hands would like to author this I, for one, would be appreciative!).
