Not sure on the currency. I thought you could get paid in Won or US dollar. Your per diem is done in both. if you fly any domestic flights or fly in or out of any other airport other than Incheon-Seoul (unless it's domestic), then you get paid per diem in Won. When flying to international destinations from Incheon-Seoul, then it's US dollars for per diem. Your recruiter should be able to wire money to any bank account you want. Hope that helps.
