Thanks for your help, Geoffrey. GSA does list a standard mileage reimbursement rate for personal aircraft, and I was under the impression that it was standard to use this. Obviously I can just do the math myself and use that rate to come up with an expense, but you seem to suggest I should only report actual expenses rather than using this rate. The rate is listed here: <a rel="nofollow" target="_blank" href="

Is that not a standard way of expensing personal aircraft use?
