I absolutely agree that current SCCMs would make great CSMs on the new fleet, but I cannot help but think the company will struggle to get enough current British Airways SCCMs to apply. We may find experienced British Airways crew, familiar with the SOPs of this business, being stepped over by SCCMs from other, very different airlines.
I guess it's a case of weighing up where the benefits lie :
The company can have existing BA crew who are experience enough to be Pursers (taking planes out in charge on shorthaul, and sometimes on longhaul) and are au fait with BA's SOPs
OR
The company can take on SCCMs from other airlines who may have LESS overall flying experience than BA's own main crew, or ground managers who have done some VCC flying, and send them out leading a crew in totally alien territory
