Cathay Pacific: about 2500 pilots, the vast majority are still on a mandatory 55.
For anyone who joined the group this year, their contract states 65. That is also the same for any direct entry freighter dudes.
With the company having successfully reduced pay and conditions over the last 10-15 years, the more senior pilots are approaching 55 with not enough to retire on (forget what you may have heard about our packages - fiscal and physical!) so they want to go to 65.
The younger guys (who are perhaps more focused on more earthly delights) think they are going to be smarter with their money than the old farts were, and would rather their command upgrades were not delayed by extending everyone to 65.
Fight looming....
