Yes. The personal days must be clearly designated when submitting a reimbursement request, and no expenses during this period can be claimed.

Airfare for the business portion of the trip is reimbursable, provided no added expense is incurred by the University. Be prepared to provide a quote showing the business-only cost of airfare if personal travel choices affect the overall cost.  

If a traveler chooses to drive for personal reasons instead of flying, OSU will reimburse the lesser of either the mileage per diem amount or the potential cost for airfare. Provide estimated costs for airfare as follows:

  • Round trip commercial airfare for the most economical direct route that would have been incurred. Quotes must be submitted with the reimbursement request.
  • Private vehicle mileage to and from the airport.
  • Lodging, meals, and incidental expenses that the traveler would normally incur with air travel. Expenses resulting from the additional time required to drive are not reimbursable.
