: Special Statutory Requirement to

Operate to or From a Part 139 Airport. Each
air carrier that provides—in an aircraft (e.g.,
airplane, rotorcraft, etc.) designed for more
than 9 passenger seats—regularly scheduled
charter air transportation for which the pub-
lic is provided in advance a schedule con-
taining the departure location, departure
time, and arrival location of the flight must
operate to and from an airport certificated
under part 139 of this chapter in accordance
with 49 U.S.C. 41104(b). That statutory provi-
sion contains stand-alone requirements for
such air carriers and special exceptions for
operations in Alaska and outside the United
States. Nothing in § 121.590 exempts the air
carriers described in this note from the re-
quirements of 49 U.S.C. 41104(b). Certain op-
erations by air carriers that conduct public
charter operations under 14 CFR part 380 are
covered by the statutory requirements to op-
erate to and from part 139 airports.

See

U.S.C. 41104(b).
