here is a global map showing eclipse visibility (assuming local weather cooperates):

for eclipse timing, see this chart:

for north america generally, the eclipse will be visible in the eastern/southern quadrant of the sky. for both flights (which generally fly NW), there is a risk that the eclipse will be directly aft and not visible at all. best of luck to you!
