When opting to drive instead of flying, will mileage be reimbursed? What documentation is required?
When the traveler decides to drive their private vehicle instead of flying to a travel destination, the traveler will be reimbursed only for the lesser of the transportation expense (either mileage reimbursement or mileage up to the airfare equivalent). Type an explanation in the Remarks section (16) on the Travel Expense Claim. Documentation showing the lowest available airfare must be attached to the Travel Expense Claim.
