One further rumour is that Jet2 will receive more B757's over the next few months taking the fleet to 6 !
I belive one of the two extra 757's will be cut up for parts. so there will be at least 4 opperational between MAN and LBA. 757's look like starting in March 2006 ish.
The rumour is also that there 737 fleat will also increase in numbers to.
