Airfare Reimbursement Details
- Standard economy class fare is recommended as the baseline. This applies to all travel (domestic or international, or any combination thereof) regardless of the purpose or fund source.
- Please note: seat selection fees, and airfare insurance (regardless of class of travel) are not reimbursable.
- When a traveler prefers to use a higher class than the one authorized for reimbursement, the traveler must pay the incremental cost of the airfare. A documented cost comparison must be attached to the Travel Authorization and Expense Report, and this cost comparison must be saved at the time of booking the airfare, as rates cannot be pulled once travel dates have passed. The most economical route is what will be reimbursed.
- Please note: Southwest Airlines is in the process of updating their fare types and you may notice different options. “Basic” is the most economical fare category and is what will be reimbursed through flights on January 26, 2026.
- If travelers choose to book upgraded fare types such as “Choice”, the traveler is responsible for saving a cost comparison at the time of booking and claiming the amount for “Basic” rather than “Choice”.
- If “Basic” is unavailable at time of booking and “Choice” must be selected, the traveler is responsible for saving documentation at time of booking proving that “Basic” was not an option for their flight route on their dates of travel, and in that case “Choice” fare may be reimbursed.
- Flights beginning January 27, 2026: Basic and Choice fares both align with CSU policy and are eligible for reimbursement.
- Any upgrades to Choice Preferred or Choice Extra will not be reimbursed, and a cost comparison at time of booking is required to claim the most economical rate.
- The University will pay the cost for checked baggage that is considered reasonable and necessary for the business purpose and length of the trip.
- Per CSU policy: Standard seat selection fees are eligible for reimbursement. While airlines often charge for seat selection separately from the base fare, these standard fees don't constitute an upgrade and are reimbursable provided they don't change the class of service from standard economy to a premium class. Examples of non-reimbursable seat purchases that change class of service are:
- Premium economy class upgrades
- First class or business class upgrades
- Extra legroom seats (marketed as 'Economy Plus,' 'Comfort+,' etc.)
