Document a Flight Comparison

Fare comparison documentation is required when any of the following occur:

  •     The trip includes a personal component.
  •     The itinerary is an indirect route.
  •     The airfare class is above economy and the comparison will be used to allocate excess costs appropriately.
  •     The most economical method of transportation is not selected for a trip, for example, a rental car is selected instead of air travel.
  •     The airfare will be charged to a sponsored research award and will be booked outside of the Stanford Travel program.

Document a Flight Comparison

The fare comparison documentation is most often in the form of a screenshot of Stanford Travel of search results taken the same day of booking from a Stanford Travel booking channel. The screenshot must visibly note the time and date of the search (i.e., from the taskbar on your desktop); include a broad set of search results (e.g., all applicable carriers); and should display the applicable parameters, such as the most direct route, excluding any personal stops and the appropriate fare class (e.g., coach, non-refundable). The expense report must include an attachment with the fare comparison documentation.

If the attached screenshot is dated post-travel, the Business Expense team will calculate an online comparison at the time of processing, and will pay based on the lesser of their own comparison or that provided by the traveler.
