1.Not enough people take the offer from Jade, - they are parking a B 744 -lack of pilots!!
2. Age 65: Typical CX management and pilots calculations...
Age 65 costs in any case more than 55 - just because many F/O,S/O's don't want to have their upgrades delayed by further 3 or MORE years, so some will resign -additional 'gap'=costs!
