41 CFR 301-53.3 - How may I use promotional materials and frequent traveler benefits?
Promotional materials and frequent traveler benefits may be used as follows:
(a) You may use frequent traveler benefits earned on official travel to obtain travel services for a subsequent official travel assignment(s); however, you may also retain such benefits for your personal use, including upgrading to a higher class of service while on official travel.
(b) If you are offered such benefits as a result of your role as a conference planner or as a planner for other group travel, you may not retain such benefits for your personal use (see § 301-53.2 of this chapter). Rather, you may only accept such benefits on behalf of the Federal Government. Such accepted benefits may only be used for official Government business.
