For hotel reimbursement, we will need a detailed receipt from the hotel itself with the cost per night broken down into room price, taxes, etc. Booking through a company like Orbitz, Expedia, hotels.com, Travelocity, etc. and using that receipt won't work for reimbursement because the price is given as a lump sum amount.
For air travel, please note that if we reimburse your airfare, the flights must comply with the Fly America Act (Federal Travel Regulations require that U.S. carriers must be used for travel that is to be reimbursed from federal grants and contracts). Note, we can only reimburse coach fare. Also, be sure to purchase your ticket directly through the airline and not through an online agent, such as Orbitz, Expedia, or Travelocity. Receipts from the online booking agents do not provide the required information needed for reimbursement. (This is the same as for the hotel reimbursement, we need to have a breakdown of the costs.)
