How many CEOs of transportation companies usually or always take their companies’ regularly-scheduled planes, trains or buses for trips?

After seeing United CEO Scott Kirby taking a private plane while United was having an operational meltdown, I assume that at least some CEOs don’t take their companies’ regularly-scheduled offerings.

If I were a board member and saw a CEO who took my company’s flights as though he or she were a regular paying passenger, I’d totally respect that and would sense that the CEO really cared about the company. And if I were a CEO, I’d certainly take my company’s regularly-scheduled flights, etc.

I have worked with a transit agency and certainly took its trains and buses, but not always. And when I worked with companies in the rail industry, I did take Amtrak, although that wasn’t required (and I didn’t work for Amtrak or an Amtrak supplier).
