such air carrier to engage in such transportation." However, as described below, the Board also had the ability to provide exemptions from this and other Act requirements. The Board, when issuing a certificate, was required to determine a carrier was "fit, willing and able" to provide air transportation, that it would obey the Board and Act, and that the certificate issuance was required by "public necessity and convenience". Further, the Board had to specify for each certificate the end and intermediate points of all routes. Thus the CAB not only determined entry into the industry, but also the specific routes a carrier served. It could also put limitations on that service. For instance, the CAB could approve a route from A to B to C but not allow the carrier to fly nonstop from A to C.

carrying passengers to the Dunes Hotel in Las Vegas for "free". The fact that transportation was provided as part of the cost of accommodation did not make the airline any less a common carrier, and therefore guilty of providing interstate air transportation without a CAB certificate. The results of such investigations were not necessarily a foregone conclusion. In 1976, the CAB ended a long investigation by deciding ZIA was, in fact, not a common carrier (and thus did not require certification), going against the decision of its own administrative law judge. Ironically, this happened only a year before ZIA separately applied for and received certification as a supplemental air carrier.

531:. In the case of air taxis, the CAB chose not to regulate. In the case of intrastate airlines, it was legally unable to. Restriction of flying to a single state was not sufficient to avoid CAB regulation; the additional measures to avoid interstate commerce were critical. Furthermore, flying within a single state was generally interpreted strictly. An aircraft flying outside the boundaries of that one state could trigger CAB authority, including, in the case of Hawaii, flying overwater between the islands, which was upheld in court as being intrinsically interstate commerce because the Federal government had domain over the seas.

Northern were memorialized in 32 pages of CAB reports, encompassing the deliberations of the (usually five but in this case four) member CAB board itself, plus the earlier deliberations of an administrative law judge in front of whom six people appeared, representing Munz and two other interested parties. At the time, Munz had six aircraft, each carrying 10 people or fewer. Further, Munz then had the same reporting requirement as carriers like United, all the usual reams of data that had to be sent to the CAB, for a carrier a tiny fraction of the size.
