I too have gone up 115 places since the last seniority list was published. There are now 321 pilots on the list compared to 451 on the last list. People are leaving all the time though. I have a job starting in August. Haven't resigned yet but may do soon and take the summer off.
Rumour control has it that there will be no 146 flying from MAN after the end of this month, just touring from other bases. This doesn't particularly appeal to me, so I might as well go ASAP.
There is only 1 MAN 146 F/O left who doesn't have a job to go to, and no more than a handful of captains.
