I agree. We try to always include travel expenses in the individual subaward budgets. This is primarily to allow subrecipient to follow their travel policies. Our university safety and risk department was also concerned about travel insurance issues if our institution pays for subrecipient travel directly, especially for international travel. In addition, if the amount of the subaward is over $25,000, paying for travel, or any other subrecipient expenses directly, as the prime recipient (rather than through the subaward) could cause an unallowed collection of IDC.
However I wondered if anyone knows of specific federal rules/clauses that we can use to support our decisions.
