DALLAS – Today in Aviation, Aer Lingus (EI) operated its maiden transatlantic flight in 1958 from Dublin (DUB) to New York (JFK) via Shannon (SNN). EI became the 17th airline in the world to commence scheduled services across the pond.
Aer Lingus established a transatlantic subsidiary known as Aerlinte Eireann to operate these services. The division would become Irish Air Lines in 1959 and Aer Lingus Irish International Airlines in 1960. This coincided with EI’s entering the jet age with the arrival of the carrier’s first Boeing 720s.
