41 C.F.R. § 301-10.260 May I use a Government aircraft for travel?
Title 41 - Public Contracts and Property Management
You may use Government aircraft for travel only if you have authorization from an executive agency under the rules specified in this part (except with regard to travel under §301–70.808 and §301–70.910). Because the taxpayers should pay no more than necessary for your transportation, generally you may travel on Government aircraft only when a Government aircraft is the most cost-effective mode of travel.
