The postings by the Korean "gentlemen" on this thread indicate (to me) that KAL's run of accidents are a long way from over!
It now appears (from comments by the Koprean contributors) Korean Air has only "tolerated" the presence of foreigners to expedite their upgrade to Group 1, and with that achieved KAL will revert to its previous structure.
Time will tell.
Certainly NOT my choice of employer, and a carrier I'll avoid at ALL costs!
