At the end of the day, whatever is written on an annoymous bulletin board is just so much hot air.
On saying that, given that your current employer (na names, no pack drill), have been less than forthcoming on their plans, add to that the entire fleet has allegedly been transferred into an Isle of Man holding company and they seem hell bent on resurecting the British Midland brand and having dual HQs I would be running for the door. In fact....
The 145 is a dying type and if the opportunity to fly an A320 exists, I see it as a no brainer.
Just my tuppenceworth.
