There is a damn good reason the likes of Queasy Jet and Ryan Scare shift their jets on at about the 5 year point, they come off warranty and the maintainence cost soar.. God knows how the MOD can justify flying around decades old Tristars and VC10's, fuel consumption alone must be horrific on the Tens, you need to fly the proverbials off them, then shift them on while they hold high residual values, Ryan Scare by having a high fleet turn over can drive down the cost of new aircraft from the manufacturers.
I realise the country is skint, but by the time you offset the higher maintenance costs, downtimes and fuel burns against a lower operating costs of a leased aircraft, I would bet the figures would open some eyes.
