You ask what a hot spare is, and you call me clueless?.... It might not be in your vocab, but trust me, you're probably in the minority who doesn't understand it.
It's a spare airplane, not in the schedule, clear of MEL's and ready to move. Is that simple enough, or do you need me to put it in Dr. Seuss language?
Again, what do you propose AA do? Fly to Seoul just because it's on the way from Europe? Have you looked at a map to see how much out of the way that might be?
You're the one saying they need a Plan B. What should it be?
How should AA avoid having crews layover in Japan?
Are APFA, APA, and the FAA going to waive contracts & duty time requirements and allow a SEL-NRT-LAX routing?
You've got lots of dramatic language, and no solutions to offer. So please. Enlighten us.
In case you didn't notice, or are Sarah Palin, there's nothing between Alaska and Japan except the Kamchakta Peninsula and Sakhalin Island. Neither place is conducive for a medical diversion, let alone a crew change. There are two quasi-suitable airports in Russia -- Magadan and Petropavlovsk. Both have 11000+ runways, but acceptable hotels and fuel quality might be a problem.

Notice that both ANC & FAI are a minimum of 3400 miles one way. You can't schedule a crew to fly 8 hours there, and 8 hours back to Alaska.
Japan is a big country. Avoiding Honshu is smart. But you don't need to avoid the entire country. Yet.
So far, Sapporo and Hokkaido seem to be largely unaffected by both the earthquake and the tsunami, aside from some damage on the south-eastern side of the island (Sapporo is on the northwest side, and it's a pretty big island).
But you're obviously the expert. I'm clueless.
So, Mr. Crew/Airplane Scheduler. What's your grand plan?
