You need to factor in that the FW market is picking up, and ex-mil RW guys can easily apply for the RAFCARS BA scheme (or Managed Path) - which requires 1500 hours of qualifying time, easily reached by those on their normal exit point. BA is not the only employer to be perfectly happy taking people on with low FW hours into the RHS.
It's a very different job, certainly, but a growing number of my ex-mil RW colleagues are now in the LHS of a big jet and very happy with the Ts and Cs.
