I know this is an old thread, but I just thought I would warn people booking on the Jin air site that they hide all sorts of extra costs until the last moment. For example, I started to book NRT-ICN-NRT and it told me the outbound fare was $50 and the return $62. But when it came time to pay they had magically added on a "fuel charge" of $58.50 additional and "taxes" of $43 that had not even been hinted at earlier, making the ticket now total $213.54!
Yes, I know a lot of airlines play games, but this was among the worst I had ever encountered as from the time I selected the fare until when it came to book it, the price almost doubled!
