41 CFR 301-70.102: -70.102 Establishing governing policies for transportation expense authorization and payment.

Agencies must establish policies and procedures governing—

(a) Who will determine what method of transportation is more advantageous to the Government;

(b) Who will approve any of the following:

(1) Use of other than coach class accommodations under § 301-10.100 of this chapter;

(2) Use of a special-reduced fare or reduced group or charter fare;

(3) Use of an extra-fare train service under § 301-10.160 of this chapter;

(4) Use of ship service;

(5) Use of a foreign ship; and

(6) Use of a foreign air carrier;

(c) When the agency will authorize use of a Government vehicle on TDY;

(d) When the agency considers the use of a POV advantageous to the Government, such as travel to and from common carrier terminals or to the TDY location. When determining whether the use of a POV to a TDY location is the most advantageous method of transportation, the agency must consider the total cost of using a POV as compared to the total cost of using a rental vehicle, including rental costs, fuel, taxes, parking (at a common carrier terminal—not to exceed the cost of taxi or transportation network company fare, etc.), and any other relevant costs;

(e) Procedures for claiming POV reimbursement;

(f) Procedures for allowing the use of a special conveyance (e.g., taxis, TNCs, innovative mobility technology companies, or commercially rented vehicles), taking into account the requirements of § 301-10.450 of this chapter;

(g) What procedures employees must follow when they travel by an indirect route or interrupt travel by a direct route;

(h) Whether to reimburse the full amount of transportation costs and in conjunction with TDY or only the amount by which transportation costs exceed the employee's normal costs for transportation between:

(1) Office or duty point and another place of business;

(2) Places of business; and

(3) Residence and place of business other than office or duty point; and

(i) Develop and issue internal guidance on what specific mission criteria justify use of other than coach class under § 301-10.100(k) of this chapter and the use of other than the least expensive compact car available under § 301-10.450(c) of this chapter. The justification criteria shall be noted on the traveler's authorization.
