NEW YORK — Tiny Allegiant Air is expanding its service again, this time with a focus on the East Coast.
The Las Vegas-based airline announced Tuesday that it is adding service to 10 new airports, including two on the far edges of the New York metropolitan area. It is also adding flights to Portsmouth, N.H., about an hour north of Boston.
Those markets represent a slight departure for the leisure-focused airline, which mostly flies from small, underserved cities to sunny vacation destinations.
Allegiant will now serve 99 airports across the country.
Last year, 7 million passengers took a flight on Allegiant. That is a sliver of the 642 million people who took a domestic flight, including 134 million on Southwest.
Most of the new flights will head to Florida.
The addition of Long Island MacArthur Airport, in Islip, N.Y. and Stewart International Airport, in New Windsor, N.Y., brings the airline closer to the lucrative New York market but still far enough away to avoid the region’s congestion and high prices. The other new cities are: Charlottesville, Va.; Clarksburg W. Va.; Concord, N.C.; Oklahoma City; Tulsa, Okla.; Syracuse, N.Y.; and Manhattan, Kan.
