Well, why would people with hours on a B777 leave their companies to join KAL? I'd say not many. Nobody wants to stay an FO forever.
Does anybody know why they need pilots with diplomas? If they do not provide upgrades for expats then there is no reason to have such a requirement. Apparently, 75% of guys can not apply because they do not have any qualifications. It's good for us who have it, less competition
I guess...
