AFAIK,
There is NO requirement for a FULL (I.e. Unfrozen) ATPL for short haul operations as you will not be acting as the PIC in a heavy position as in LH.
I believe (from a buddy of mine who will be interviewing the lucky applicants
) that the wording of the website means CPL with full exam passes. Thus fATPL(A).
A simple phone call could clear it all up rather than rely on a Rumour website.
(P.S. Yes, I do work for BA!)
