Travel is a two-step process for the University.

  1. Submit travel pre-approval before trip.
  2. Submit expense report after trip to request reimbursement or reconcile p-card transactions.

Employees who travel for University business MUST submit a travel pre-approval in Chrome River. The pre-approval must be in approved status (approved by Accounts Payable) before making travel purchases. A travel pre-approval is required for all travel, regardless of reimbursement.

  • If additional approval is separately mandated by department/chair/dean/VP be sure to include that approval in the backup documentation in Chrome River.
  • The Provost requires Faculty to obtain dean approval before travel. Attach memo/email to travel pre-approval attachments. Chrome River does not route for dean approval.
  • In-state – approved at least 3 days prior to date of travel
  • Out-of-state – approved at least 10 days prior to date of travel
    • Note: An “After the Fact “(ATF) explanation must be submitted with Chrome River pre-approval if the travel pre-approval was not submitted according to the above timelines. ATF pre-approvals will be routed to the Vice President for approval.

Travelers using federal grant funds must comply with the Fly America Act. See https://www.gsa.gov/policy-regulations/policy/travel-management-policy/fly-america-act. Travelers that extend trips for personal business must provide airline documentation of the flight cost for the business return date and the personal return date. If the business return date is less expensive than the personal return date, then the smaller amount will be reimbursed.

  • Three airline quotes must be included with the pre-approval; the chosen airfare must be the least expensive of the 3 quotes.
  • Quotes do not need to be from different airlines.
  • Provide an explanation if the least expensive option is not used.
  • If a personal vehicle is used in lieu of air travel, mileage reimbursement cannot exceed the cost of coach/economy airfare.
