Sec.  372.117  Motor transportation of passengers incidental to 
transportation by aircraft.

    (a) Passengers having an immediately prior or subsequent movement by 
air. The transportation of passengers by motor vehicle is transportation 
incidental to transportation by aircraft provided (1) that it is 
confined to the transportation of passengers who have had or will have 
an immediately prior or immediately subsequent movement by air and (2) 
that the zone within which motor transportation is incidental to 
transportation by aircraft, except as it may be individually determined 
as provided in section (c) herein, shall not exceed in size the area 
encompassed by a 25-mile radius of the boundary of the airport at which 
the passengers arrive or depart and by the boundaries of the commercial 
zones (as defined by the Secretary) of any municipalities any part of 
whose commercial zones falls within the 25-mile radius of the pertinent 
airport.
    (b) Substituted motor-for-air transportation due to emergency 
conditions. Transportation of passengers by motor vehicle is 
transportation incidental to transportation by aircraft if it 
constitutes substituted motor-for-air service performed at the expense 
of the air carrier in emergency situations arising from the inability of 
the air carrier to perform air transportation due to adverse weather 
conditions, equipment failure, or other causes beyond the control of the 
air carrier.
    (c) Individual determination of exempt zones. Upon its own motion or 
upon petition filed by any interested person, the Secretary may in an 
appropriate proceeding, determine whether the area within which the 
transportation by motor vehicle of passengers having an immediately 
prior or subsequent movement by air must be performed, in order to come 
within the provisions of paragraph (a) of this section, should be 
individually determined with respect to any particular airport or city 
served by an airport, and whether there should be established therefor 
appropriate boundaries differing in extent from this defined in 
paragraph (a)(2) of this section.
    (d) Exempt zones and operations--(1) Dulles and Baltimore-Washington 
International Airports. The transportation by motor vehicle, in 
interstate or foreign commerce, of passengers, having an immediately 
prior or subsequent movement by air, between Dulles International 
Airport, near Chantilly, Va., and Baltimore-Washington International 
Airport, near Baltimore, Md., is partially exempt from regulation under 
49 U.S.C. 13506(a)(8)(A).
    (2) Savannah, Ga., Airport. The transportation by motor vehicle, in 
interstate or foreign commerce, of passengers, having an immediately 
prior or subsequent movement by air, between Savannah, Ga., Airport and 
all points on Hilton Head Island, SC, is partially exempt from 
regulation under 49 U.S.C. 13506(a)(8)(A).
    (3) Chicago O'Hare International Airport (Chicago, Ill.). The 
transportation by motor vehicle, in interstate or foreign commerce, of 
passengers, having an immediately prior or subsequent movement by air, 
between O'Hare International Airport, at Chicago, Ill., on the one hand, 
and, on the other, points in Indiana on and north of U.S. Highway 30 and 
on and west of Indiana Highway 49, is partially exempt from regulation 
under 49 U.S.C. 13506(a)(8)(A).
