*Aircraft management office.* An agency component that has management control of Federal aircraft used by the agency or of aircraft hired as commercial aviation services (CAS).
*Approved accommodation.* Any place of public lodging that is listed on the national master list of approved accommodations.

*Automated Relocation Management System.* An automated relocation management system is a system that integrates into a single, electronic environment, information related to all aspects of employee relocation.
*Coach class.* The class of accommodation that is normally the lowest class of fare offered by common carriers regardless of terminology used. For reference purposes only, coach class may also be referred to as tourist class, economy class, steerage, or standard class.
(1) If an airline flight has only two seating sections available but equips both with one type of seating, (*i.e.,* seating girth and pitch are the same in both sections of the aircraft), and the seats in the front of the aircraft are fare coded as full fare economy class, and only restricted economy fares are available in the back of the aircraft, then the entire aircraft is to be classified as coach class.
(2) Coach class seating upgrade options are seat choices with increased amenities or services within the coach class seating area that are available for a fee, and are not considered a new or higher class of accommodation from coach as the seat is lower than other than coach class accommodations in terms of cost and amenities (*e.g.,* seating girth and pitch, priority boarding, luggage allowance, expedited food/drink service). Use of upgraded coach class seating options is generally a traveler's personal choice and therefore is at the traveler's personal expense. However, the agency approving official may approve reimbursement of the additional seat choice fee according to part 301-13 of this subtitle or when determined by the agency to be advantageous to the Government.
*Commercial Aviation Services (CAS).* CAS include, for the exclusive use of an executive agency—
(1) Leased aircraft;

*Contract carrier.* U.S. certificated air carriers which are under contract with the Government to furnish Federal employees and other persons authorized to travel at Government expense with passenger transportation service.

*Contract City Pair Program.* A mandatory use (see § 301-10.110 of this subtitle for required users) Government program that provides commercially available scheduled air passenger transportation services to persons authorized to travel directly at the Government's expense. The City Pair Program offers negotiated firm-fixed-price fares on one-way routes between airports that apply in either direction of travel. Fares may be issued using one of the following fare types, or others that the contract City Pair Program may solicit:
(1) *Capacity-controlled coach class contract fare* (_CA). A contract City Pair Program coach class fare that is less expensive than the unrestricted coach class contract fare (YCA), but has limited inventory availability, meaning, once the flight reaches a certain capacity, _CA fares may no longer be available for booking. Unlike YCA fares, _CA fares are restricted by the availability of seats. Accordingly, early booking may increase the likelihood of booking a _CA fare.
(2) *Unrestricted coach class contract fare* (YCA). A contract City Pair Program coach class fare that is more expensive than a _CA fare, but offers last seat (inventory) availability (unless a flight is already sold out), meaning, as long as coach class inventory is available to sell on the flight, the Government traveler can purchase it.
(3) *Contract business fare* (_CB). Contract fare offered by carriers in some domestic and international line item markets for business class service.
(4) *Contract premium economy fare* (_CP). Contract fare offered by carriers in international line items markets for premium economy service. This is a separate class of service from coach class.

(9) Are willing promptly to disclose, if required by the agency, any dissolution or material change in the status of the domestic partnership; and
