Well False Capture from a personal point of view I hope the 146's stay till I can make good my escape. I've heard a rumour that they are only leased on a monthly basis, except the festering junk heap GMABR which is owned by the company. As such it should be easy to dispose of them when required.
At the moment though, they are the only >50 seat A/C at MAN and are required for the MXP and MAD routes, so I think they will stay for a while.
I've got to agree with Bacon slicer. This company is ****ed. I only wished I'd realised this a little sooner, and made more positive efforts to leave.
