41 CFR § 301-10.117
May I keep compensation an airline gives me for voluntarily vacating my seat on my scheduled airline flight when the airline asks for volunteers?
June 9, 2020
Yes:
(a) If voluntarily vacating your seat will not interfere with performing your official duties; and
(b) If additional travel expenses, incurred as a result of vacating your seat, are borne by you and are not reimbursed; but
(c) If volunteering delays your travel during duty hours, your agency will charge you with annual leave for the additional hours.
