> Other nice thing: no potential for your entire eclipse hunting expedition to be ruined by bad weather. There is definitely a possibility of there being cloud cover, even at FL300, to cover the path of that flight. Assuming they would be allowed up to fly above FL380 by ATC, even less likely, but still not zero potential.
