Fat Dog,
Look on the brighter side, at least you got a good taste of how you will be treated in KAL.
You REALLY gotta hate your present job and desperate enough to join them on the 737. I assure you that you WILL have more than your fair share of issues, flying domestically with all the "friendly" people in KAL.
Oh ya, haejangkuk was completely right, that absolutely big fat ZERO chance of you getting on the 777 now, once they offered 737.
