Subpart B—Common Carrier Transportation Airline

§ 301-10.100 Use of other than coach class accommodations.

Employees are authorized to use the least expensive class of accommodations (e.g., coach class) necessary to meet their needs and accomplish the agency's mission. Employees may be authorized to use accommodations other than coach class only when the agency head or designee specifically authorizes or approves such use under specific circumstances. Except as otherwise indicated in this section, agencies should authorize the lowest level of other than coach class accommodations, starting with premium economy, then business, then first, with much higher agency scrutiny on each increase in class level authorized. The agency head or designee may authorize other than coach class accommodations when—

(a) Such accommodations are required to accommodate a medical disability or other special need (see part 301-13 of this subchapter);

(b) Exceptional security circumstances, as determined by the agency, require other than coach class accommodations;

(c) Regularly scheduled service between origin and destination points provides only non-coach class accommodations;

(d) Common carrier costs are paid in full through agency acceptance of payment from a non-Federal source in accordance with chapter 304 of this subtitle;

(e) The use results in overall cost savings to the Government by avoiding additional subsistence costs, overtime, or lost productivity time;

(f) No coach class space is available that allows arrival in time to accomplish an urgent mission;

(g) Coach class accommodations on an authorized foreign carrier do not provide adequate health or sanitation standards;

(h) The origin and/or destination is/are OCONUS and scheduled flight time, including stopovers and change of planes, is in excess of eight hours, in which case agencies can authorize or approve premium economy class accommodations;

(i) The origin and/or destination is/are OCONUS and scheduled flight time, including stopovers and change of planes, is more than 14 hours, in which case agencies can authorize or approve business class accommodations;

(j) No coach class, premium economy class, or business class accommodations are available on a common carrier scheduled to leave within 24 hours of the proposed departure time, or scheduled to arrive within 24 hours of the proposed arrival time, in which case agencies can authorize or approve first class accommodations;

(k) Such accommodations are required because of agency mission; or

(l) The agency determines other than coach class accommodations are more advantageous than authorizing a rest period.

§ 301-10.101 Changes to or non-use of common carrier reservations.

Employees must take action to change or cancel their common carrier reservation and report any changes or cancellations as prescribed by their agency. Failure to do so may subject the employee to liability for any resulting losses.

§ 301-10.102 Handling of unused Government transportation items.

Any unused ticket or refund applications are the property of the Government and must be returned to the agency in accordance with agency procedures. Employees are not authorized to receive or keep a refund or credit for unused transportation, except as provided in § 301-10.123.

§§ 301-10.103-301-10.109 [Reserved]

Use of Contract City Pair Program Fares

§ 301-10.110 Requirement to use contract City Pair Program fare.

(a) Employees of an “agency” as defined in § 300-1.1 of this subtitle must use a contract City Pair Program fare for scheduled air passenger transportation service unless specific exceptions exist in § 301-10.111.

(b) When a carrier offers both a lower-cost capacity-controlled coach class contract fare (_CA) and an unrestricted coach class contract fare (YCA), employees must use the lower-cost fare when it is advantageous and meets mission needs.

(c) Employees of the Government of the District of Columbia, except the District of Columbia Courts, are not eligible to use contract City Pair Program fares.

§ 301-10.111 Exceptions to contract City Pair Program fare usage.

The agency head or designee may authorize use of a non-contract fare when—

(a) There are no accommodations available on any scheduled contract City Pair Program flight arriving to the employee's destination in time to accomplish the travel purpose or use of contract service would require the employee to incur unnecessary overnight lodging costs which would increase the total cost of the trip;

(b) The contractor's flight schedule is inconsistent with explicit policies of the Federal department or agency with regard to scheduling travel during normal working hours;

(c) A non-contract carrier offers a lower fare to the general public that, if used, will result in a lower total trip cost to the Government (the combined costs of transportation, lodging, meals, and related expenses considered); or

(1) The exception in this paragraph (c) does not apply if the contract carrier offers the same or lower fare and has seats available at that fare, or if the fare offered by the non-contract carrier is restricted to Government and military travelers performing official business and may be purchased only with a contractor-issued charge card, centrally billed account (e.g., YDG, MDG, QDG, VDG, and similar fares) or GTR where the two previous options are not available.

(2) [Reserved]

(d) Cost effective rail transportation is available and is consistent with mission requirements.

(e) A group of 10 or more passengers traveling together on the same day, on the same flight, for the same mission, requiring group integrity and identified as a group by the travel management service upon booking is not a mandatory user of the Government's contract City Pair Program fares. For group travel, agencies are expected to obtain air passenger transportation service that is practical and cost effective to the Government.

(f) Contractors are not authorized to use contract City Pair Program fares to perform travel under their contracts.

(g) Carrier preference is not a valid exception for using a non-contract City Pair Program fare.

§ 301-10.112 Liability for unauthorized non-contract carrier use.

Employees are responsible for any additional costs or penalties incurred by using a non-contract carrier when contract service is available and no authorized exception applies.

Airline Accommodations

§§ 301-10.118-301-10.121 [Reserved]

When performing official travel and a carrier denies a confirmed reserved seat, employees must provide any liquidated damages payment to their agency in accordance with their agency's procedures.

§ 301-10.123 Compensation for voluntarily vacating a seat.

(a) Employees may keep airline compensation for voluntarily vacating a seat under two conditions:

(1) Voluntarily vacating the seat will not interfere with performing official duties; and

(2) Any additional travel expenses resulting from vacating the seat are personally borne and not reimbursed by the Government.

(b) If volunteering causes travel delays during duty hours, the agency will charge the employee annual leave for the additional hours.

§ 301-10.124 Use of reduced group or charter fares.

Employees may use reduced group or charter air fares only when the agency has determined, on an individual case basis before travel begins, that such a fare is cost-effective. Chartered aircraft are subject to Government aircraft rules, and executive branch agencies must follow Office of Management and Budget Circular A-126 and part 102-33 of this title when determining cost-effectiveness.

(e) A U.S. flag carrier involuntarily reroutes the employee's travel onto a foreign carrier.

(f) Service on a foreign air carrier would be three hours or less, and use of the U.S. flag carrier would at least double the employee's en route travel time.

(g) When the costs of transportation are reimbursed in full by a third party, such as a foreign government, international agency, or other organization.

(h) For travel solely outside the U.S., use of an available U.S. flag air carrier when compared to using a foreign air carrier will increase the number of aircraft changes the employee must make en route by 2 or more; or extend the travel time by 6 hours or more; or require a connecting time of 4 hours or more at an overseas interchange point.

(a) If a U.S. flag air carrier offers nonstop or direct service (no aircraft change) from origin to destination, the employee must use the U.S. flag air carrier service unless such use would extend travel time, including delay at origin, by 24 hours or more.

(b) If a U.S. flag air carrier does not offer nonstop or direct service (no aircraft change) between origin and destination, the employee must use a U.S. flag air carrier on every portion of the route where it provides service unless, when compared to using a foreign air carrier, such use would:

(1) Increase the number of aircraft changes made outside of the U.S. by 2 or more;

(2) Extend travel time by at least 6 hours or more; or
