If I were the company management, would provide a taxi/limo for the longer travel distances, as a usual course.
Having said this, if this was a one off scenario, what's the beef?
If a flight was to have been delayed if said CC member did not comply, most company management would ge highly agitated if the employee stood down, refusing to travel.
This might result in a 'don't come Monday' letter.
There must be plenty at the HR door wanting a job.
