Thanks to all for the information!
robert, thanks for that link. It is very helpful.
Willy. I will talk to the pilots. I'd prefer not to end up in North Korea myself.
Arnold, after looking it up, that would be where my stopover is also, in Incheon. I haven't picked a specific date yet, as I'm talking to the lady I am planning on meeting about the best time to visit. (yes, guys, I'm only visiting one lady. I'm willing to take my chances!
)
Jason B, thanks for that information. I will definitely check into it.
Gerry, thanks also for that advice. I will set my alarm on my cell phone (or I'll bring a cheap digital wrist watch with an alarm) if I feel drowsy to insure I don't miss a flight!
