I have heard, very recently, from within BA that the company may be looking at opening their recruiting (can't say when, but I got the impression it will be before next summer) to non-type rated military pilots. It seems that they want to recruit from mixed backgrounds, but it might only be a small group though - in the order of 20 or so. I cannot say whether they will give some/any preference to military pilots who were formerly in the hold-pool. I would hope so, but who knows .....
Commiserations to those who have not been successful in their recent applications, and best of luck to those who are 'in the pipeline', or still waiting.
