Travel plans should be outlined clearly as to purpose, travelers, destinations, dates, and costs. Foreign travel must be outlined and justified fully in relation to the project's outcome. Normally, air travel must be at economy fare, and (for federal grants and some private sources) use of U.S. carriers is required for foreign travel except in special circumstances. Some agencies require prior approval for foreign travel, while many others have waived this requirement.
