Chances are they won't fly in the same location. Lufthansa has already rerouted flights scheduled to go over around the eastern Ukrainian airspace, I can't imagine Malaysian not following suit. It's not like they have the best track record at the moment.
UPDATE: The FAA just prohibited flying over that airspace. So I would be blown away if your plane continued flying there.
UPDATE: Air France now, too.
UPDATE: Even three Russian airlines are re-routing, which will be difficult for some flights heading west from Moscow. No word from Malaysian... they've probably got bigger fish to fry at the moment.

UPDATE: British Airways and Air Canada, too.
