There are still some travel restrictions in place in response to the coronavirus (COVID-19). Check out CU's Coronavirus Travel Guidance. (Where campus-specific guidance is more restrictive than CU System procedures, you are responsible for following campus guidance.)

No Outside Internet Airfare Bookings

Among the COVID-related travel restrictions that continue to be in effect (as outlined on the PSC Updates Related to the Coronavirus-Travel website) is the restriction on outside internet airfare bookings. External internet airfare purchases are not allowable during the coronavirus health crisis. All University-related travel must be booked through the University’s travel management program: either online in the Concur Travel & Expense System or through a travel agent with Christopherson Business Travel (CBT). This allows us to monitor your travel location and provide assistance if you encounter a health, emergency, or security issue – especially important during situations such as the current coronavirus situation. If you book CU business travel through the internet during this time – March 13, 2020 through the end of the travel restrictions period (as announced by the PSC) – you will not be reimbursed for your out-of-pocket airfare bookings.
