The first Martin 202 began service with Allegheny on June 1, 1955. The Martin 202, like the DC-3, was unpressurized, but the Martin Executive, as they were called, quickly became a favorite among businessmen. On January 1, 1956, Allegheny was issued a permanent certificate to carry passengers by the C.A.B. By now, Allegheny had expanded to sixty cities with a fleet of 14 DC-3s and 5 Martin 202s; the airline was so happy with the performance and range of the Martin 202 that it would eventually acquire and operate a total fleet of 18 aircraft.
