41 CFR § 301-53.4
May I select travel service providers for which my agency is not a mandatory user in order to maximize my frequent traveler benefits?
June 9, 2020
No, you may not select a traveler service provider based on whether it provides frequent traveler benefits. You must use the travel service provider for which your agency is a mandatory user. This includes contract passenger transportation services and travel management services. You may not choose a travel service provider to gain frequent traveler benefits for personal use. (Also see §§301-10.109 and 301-10.110 of this chapter.)
