[Code of Federal Regulations] [Title 41, Volume 4] [Revised as of July 1, 2002] From the U.S. Government Printing Office via GPO Access [CITE: 41CFR301-10.107] [Page 25-26] TITLE 41--PUBLIC CONTRACTS AND PROPERTY MANAGEMENT CHAPTER 301--TEMPORARY DUTY (TDY) TRAVEL ALLOWANCES PART 301-10--TRANSPORTATION EXPENSES--Table of Contents Subpart B--Common Carrier Transportation Sec. 301-10.107 When must I use a contract city-pair fare? You must always use a contract city-pair fare (an Internet list of city-pairs is available at http://pub.fss.gsa.gov/services/citypairs), if you are a civilian employee of an agency (see Sec. 301-1.1 of this chapter), unless one or more of the following conditions exist(s): (a) Space or a scheduled contract flight is not available in time to accomplish the purpose of your travel, or use of contract service would require you to incur unnecessary overnight [[Page 26]] lodging costs which would increase the total cost of the trip; or (b) The contractor's flight schedule is inconsistent with explicit policies of your Federal department or agency with regard to scheduling travel during normal working hours; or (c) A non-contract carrier offers a lower fare available to the general public, the use of which will result in a lower total trip cost to the Government, to include the combined costs of transportation, lodging, meals, and related expenses. Note to paragraph (c): This exception does not apply if the contract carrier offers a comparable fare and has seats available at that fare, or if the lower fare offered by a noncontract carrier is restricted to Government and military travelers on official business and may only be purchased with a GTR, contractor-issued charge card, or centrally billed account (e.g., YDG, MDG, ODG, VDG, and similar fares); or (d) Rail service is available and such service is cost effective and consistent with mission requirements; or (e) Smoking is permitted on the contract flight and the nonsmoking section of the aircraft for the contract flight is not acceptable to you.
