a. General. Travel costs are allowable for expenses for transportation,
lodging, subsistence, and related items incurred by employees traveling on
official business. Such costs may be charged on an actual cost basis, on a per
diem or mileage basis in lieu of actual costs incurred, or on a combination of
the two, provided the method used is applied to an entire trip, and results in
charges consistent with those normally allowed in like circumstances in
non-federally-sponsored activities. Notwithstanding the provisions of section
23, travel costs of officials covered by that section, when specifically
related to Federal awards, are allowable with the prior approval of a grantor
agency.
b. Lodging and subsistence. Costs incurred by employees and officers
for travel, including costs of lodging, other subsistence, and incidental
expenses, shall be considered reasonable and allowable only to the extent such
costs do not exceed charges normally allowed by the governmental unit in its
regular operations as a result of the governmental unit's policy. In the
absence of a written governmental unit policy regarding travel costs, the rates
and amounts established under subchapter I of Chapter 57 of Title 5, United
States Code "Travel and Subsistence Expenses; Mileage Allowances," or by the
Administrator of General Services, or the President (or his designee) pursuant
to any provisions of such subchapter shall be used as guidance for travel under
Federal awards (41 U.S.C. 420, "Travel Expenses of Government Contractors").
c. Commercial air travel. Airfare costs in excess of the customary
standard (coach or equivalent) airfare, are unallowable except when such
accommodations would: require circuitous routing, require travel during
unreasonable hours, excessively prolong travel, greatly increase the duration
of the flight, result in increased cost that would offset transportation
savings, or offer accommodations not reasonably adequate for the medical needs
of the traveler. Where a governmental unit can reasonably demonstrate to the
awarding agency either the nonavailability of customary standard airfare or
Federal Government contract airfare for individual trips or, on an overall
basis, that it is the governmental unit's practice to make routine use of such
airfare, specific determinations of nonavailability will generally not be
questioned by the Federal Government, unless a pattern of avoidance is
detected. However, in order for airfare costs in excess of the customary
standard commercial airfare to be allowable, e.g., use of first-class
airfare, the governmental unit must justify and document on a case-by-case
basis the applicable condition(s) set forth above.
d. Air travel by other than commercial carrier. Cost
of travel by governmental unit-owned, -leased, or -chartered
aircraft, as used in this section, includes the cost of lease, charter,
operation (including personnel costs), maintenance, depreciation, interest,
insurance, and other related costs. Costs of travel via governmental unit-owned,
-leased, or -chartered
aircraft are unallowable to the extent they exceed the cost of allowable
commercial air travel, as provided for in subsection c.
