I believe BA had already extended it to 60 a month or so ago for those who wish to go on until then, with a view to increasing it further or eliminating it in accordance with the EU directives once the procedures for establishing the suitability of older pilots are established - and once the French bother complying with EU directives.
Ironic really that we have the best compliance with EU directives when the French are supposed to think that they are the centre of the EU. I digress...
