Stimpy...You might get lucky next week. I've noticed that ANA's been operating 744s LAX-NRT daily the past two weeks or so--saw an ANA 747 depart LAX just yesterday. Pretty sure these are the same 747s that they operate to LHR, FRA and JFK with the new F.
One of their 777ERs is in the repair shop after its wing clipped a UA 777 at SFO, so this must be a temporary subsitution.
Good luck to you and let us know what happens!
