The FR scenario is a bit unique. BA may possibly be looking at a few DEPs from Ryanair, however if it is a full JAR UK issued CPL or ATPL that is required then it rules them out in my opinion. I reckon the guys within BA will have enough inside knowledge available to know that FR guys have IAA issued licences. Will they make allowance, we'll just have to wait and see. Even without them, the volume of current 737 jocks applying will be pretty fierce.
