For each trip, the proposed destination, purpose and duration of the trip should be described. An estimated breakdown of expenses for each person traveling should include:
- round trip coach air fare
- per diem or living expenses
- other related expenses such as ground transportation, conference registration fees, and short-term Visa fees, etc.
For use in federal projects, the General Services Administration publishes the maximum allowable Federal per diem rates for U.S. and foreign cities.
The Federal Government imposes strict regulations regarding the use of U.S. flag carriers and the class of ticket a grantee must purchase. See Fly America Act
