What is the university best practice for pulling an airfare cost comparison when blending business travel with leisure?

The best practice is to pull the airfare cost comparison within 24 hours of the actual purchase (when reasonably possible). 

Comparisons should be pulled from a full service agent with the contracted travel agency or through Concur (online booking tool).  The comparison should include the date of the request and the lowest reasonable coach/economy quote in respect to both the business portion and the business/leisure portion.  

The cost comparison should be attached to the Travel Comparison Worksheet and uploaded to the Spend Authorization and be available for processing with the Expense Report for the airfare.
