There is a lot of overhead to commercial air travel, even when it's first/business.

You're probably right that it's more reasonable for flying overseas. But for local travel, limitations on timing, connections, and airports served turn into a big waste of time. It's an analysis that has to be made about the value of the CEO or whoever's time, but it's not black and white, and a couple million bucks vs a few 100k for way better scheduling could easily be worth it.
