Regarding comments on LIFO, the Transport Select Committee yesterday required data on average ages for the various groups affected by redundancy/CRS compared to those retained. When this data materialises there may well be redress/scrutiny with relation to the 2010 equality act.
Sorry to say that age has little to do with it. BA recruit a selection of ages as it recruits Ab-Initio pilots, Direct entry pilots from other airlines and ex military pilots. So you will find a 'joining age' spread from '20 ish' to '40 ish' without a problem. It also seems that BASSA were quit happy to follow LIFO with respect to the MFU from what can be gather from social media.
