Let's cut through the horse****.

I'm a private pilot (no, I'm a commercial pilot, CFI, A&P, IA but let
that go for the moment).

My company sends me to a conference. The company policy pays IRS
mileage (48.5c a mile) for me to get there by private vehicle.
Vehicle is automobile, wagon train, muleback, or any other method I
choose.
The company policy says that I can go by myself or carry as many
other employees as I wish in my private vehicle for the same 48.5
cents a mile.
I load up Gerry, Kelly, Sam and myself into the airplane and fly to
the conference. I'm not paid to get to the conference, just be a
company employee while I am at the conference.

I get home without incident.

I bill the company for what would have been automobile mileage and
multiply it by 48.5 cents a mile and submit it. Company pays. Case
closed.

Let's modify that some and see if it would still be FAA legal.

Gerry, Kelly and same get the same 48.5c/mile from the company and
give it to you.

As long as the total of reimbursements are less than 50% of the cost of
the flight, it doesn't conflict with the FARs. OTOH, if someone has a bug
up their posterior and wants to hassle you, they don't have to be right or
interpret the FARs correctly.
