Not owned by KAL Pilots? That’s easy. Form a company (ABC company) in some offshore region.
Being established for an x number of year may be different.
If ABC Company says to KAL that they have 20 or more pilots willing to join and no one is with the other companies, KAL may waive that rule if they are the only contract company that has pilots willing to join(say 10 777 Captains and 10 747-400 rated pilots).
The idea is there, will anyone with entrepreneur skills willing to act on it?
