Ludington Airline

Ludington Airline was an airline in the northeastern United States begun in 1929 with an investment of at least $1 million from Charles Townsend Ludington and his brother Nicholas.
In its first year, the airline reportedly had 66,000 passengers and a profit of $8,000. Pennsylvania Railroad handled Ludington ticketing and allowed buses for transfers at New York Penn Station. Ludington brochures advertised "Plane Service, like Train Service" as their mode of operation.
With increased competition, a reorganization of leadership, and government pressure toward airline monopolization, Ludington sold to Eastern Air Transport in 1933.
