If all these pilots are queuing up to join BA then why have they had to drop the experience requirements from a type rating on 744,777 or 320 to just 400 hours on any large aircraft? Why are they calling up people who were rejected last year and asking them to have another go. Why are they having to place the 200hr SSPs at LGW because DEPs are refusing to join if they go there? Why are the ex-bmi guys in A position that they can insist on long haul or they won't join?
I think you overestimate the number of experienced pilots who are willing to give up jobs and potential commands in regional based airlines to move or commute to the LHR area and spend 10+ years in the right hand seat. The lions share of the DEP intake has come from bmi and My Travel, people who were already based in the South East. Once that supply is exhausted then what next?
