Aircraft costs for the Secretary's travel come out of one account
What the document says“All official costs associated with the use of Government aircraft by Department of Homeland Security personnel to support official travel of the Secretary and the Deputy Secretary shall be paid from amounts made available for the Office of the Secretary.”
Section 104. Where department personnel use government aircraft to support official travel by the Secretary or the Deputy Secretary, the cost is charged to the Office of the Secretary rather than to the component that owns or flies the aircraft.
What the document actually says“All official costs associated with the use of Government aircraft by Department of Homeland Security personnel to support official travel of the Secretary and the Deputy Secretary shall be paid from amounts made available for the Office of the Secretary.”
The head of the department may fly on a federal plane. If so, the bill goes to their own office.
The Coast Guard and the border agency own planes. Their crews may fly these trips. The bill still goes to the Secretary's office.
