So you're suggesting that NW regularly ferries empty 757s via ANC back and forth to Asia?

That cannot POSSIBLY make business sense for NW. Why put the extra cycles on the airframes AND pay for fuel just to take them back-and-forth!?

My guess is that those 757s stay in Asia (on a regular basis I mean -- of course they may need to come to the mainland US on occasion for whatever reason). I would just love to know how many of them are out there.
