4921102: Air Courier Services
Establishments primarily engaged in furnishing air delivery of
individually addressed letters, parcels, and packages (generally
under 100 lbs.), except by the U.S. Postal Service. While these
establishments deliver their consignment by air, the initial pick-up
and the final delivery are often made by other modes of
transportation, such as truck, bicycle, or motorcycle. Separate
establishments of air courier companies engaged in providing pick-up
and delivery only, "drop-off points", or distribution centers are
all classified here.
