If a trip is cancelled due to no fault of the traveler, we generally allow those costs to be charged to the award. A credit is usually issued for the flight, and it is the department's responsibility to monitor the flight credits. If the credit ends up getting used to benefit another project, then the department needs to move the expenses to the proper funding source. If the award ends, and the department is unable to book a replacement flight and/or the credit expires before it can be used, then the expense should be moved to a nonsponsored funding source.
