American assigned American Eagle to launch new service between New York’s LaGuardia Airport and Cincinnati with a $238 roundtrip introductory fare. The airline will use a combination of ERJ 135s, 140s and 145s on the four roundtrips daily on the route. The new Cincinnati service, which began April 10, is part of American's initiative to become New York’s airline of choice. American is increasing its presence in New York City by adding a number of new routes, completing its new $1.1 billion terminal at JFK International Airport and upgrading amenities on international and transcontinental flights.
