This seen today, and apparently approved by BA for public viewing:
Flight Ops anticipate a requirement for pilots after 1 Apr 11 to support growth in the Summer and Winter 11 flying programme. A business case has been submitted to secure approval to recruit pilots in the FY 2011/12. The exact pilot establishment required is still uncertain but we do not anticipate the number required to exceed 100 pilots in the next 12 months.
It does appear that it will be
type-rated pilots only, initially at least (for the first year?). I have seen no official confirmation what those types are, but previous posts suggesting A320/B737 sound feasible.
