Are you trying to say here that more NK airplanes are going overseas? If so I don't think the article implies that at all. As someone else stated the article says "brand new airplane." That right there says that the airframes are not coming from NK. I know the media has been known to make mistakes once and a while as well, however I don't think that's it's real rational to start assuming that every time a airline that Indigo has it's hand in get a new jet that it's coming from NK.
If that's not what you're trying to say than forget what I just said but I think that's what a lot of folks are taking from it.
