As a 737 FO you will be flying with young local Captains most of who I heard were nice as well as with more experienced ex-pats. I know 3 guys who fly (one of them I should say flew)there as FO in the 737. Training got tough at some point like for everybody else, again depending on the instructor you have but at the end they all made it . One left for the middle east after a short period of time. The other 2 as far as I know are still flying there. As I said, life is better once you pass the training and are flying the line. Routes are within south Korea and other places in Asia like China, Japan and as far as Bangkok. Communting contract is the same as for the other fleets. Training is around 3 months. Like I said before, once you finish training is not a bad place to work. Best of luck.
