330's go a lot of places. What has already been mentioned is correct, and in addition, they also service Bangkok (Pusan - BKK), Brisbane, Nadi, Zurich, Amsterdam, Hanoi, Ho Chi Minh, Jakarta, Kuala Lumpur, and Mumbai off the top of my head.
Generally local F/O's enjoy flying with foreign Captains, of course, like anywhere, there is the odd exception to the rule I guess.
As for the any connections to the strike, well, you have to remember that the longer the Korean pilots strike, the more the chairman dislikes them, and the more foreign pilots are looked upon favourably by the company....
