Nothing like as good as with the airlines! One of the biggest areas of concern in the RAF at present is that, unlike in the rest of the 21st century employment, the pension is NOT based on your final salary. 'They' still haven't realised that Flying Pay IS part of one's salary, hence those lucky enough to remain flying only get a pension based on about 75% of their final salary. But if you were Wg Cdr paperclips on the same salary as Sqn Ldr A2 QFI, IRE, etc etc who'd given years of service, then you would get a pension based on 100% of your final salary!
Hence unless the blunt ones who make these decisions start paying pensions based on final (or best of the last 3) year's salary, people will just leave for the airlines as soon as they've achieved their 2000 hours' accreditation rights.............
