speaking of ground transportation as a deviation expense.....

I was flying with a guy a few days ago, and he asked me if he could claim the cost of a rental car as a normal deviation expense (vs. taxi, limo, etc.)

I didn't know the answer, and the contract only says "vendor for surface transportation" - kinda vague.

I never have tried it, but wondering if anyone else has ever done a rental car reimbursement (not during ITU - just on a regular deviation)??
