Overly restrictive business flying requirements.

Hold it there. This brings up the debate of relative safety.
Statistically, travel by train has about the same safety record as
travel by commercial airlines in terms of fatalities per
passenger-mile. It is far safer than GA, or other non-scheduled
commercial air travel. Long distance buses are by far the safest mode of
all.

Of course, fatality isn't really the driving factor in the corporate liability.
Being disabled on company business is probably going to cost them more.
