I don't know about the normal business travelers but the wealthy ones are flying like crazy. NetJets has had to suspend 25hr flight card sales on all fleet types now because they can't keep up with the demand. And hiring plans for 2021 have gone from 100 to 300 pilots. FSI is training instructors as fast as they can get them (which isn't easy with current demand for pilots) to support the rush of initial ground schools.
