Low-cost JetBlue Airways said on Tuesday it may add flights between New York and Boston to its roster once its new Embraer 190 airplanes join its fleet.

The first 100 seat Embraer 190, is scheduled for delivery in August and will start flying in October, JetBlue Chief Executive David Neeleman said at a news conference at a tourism and aviation trade fair in Sao Paulo.

"We should have seven 190s by the end of the year," he said. "Next year we should get 18 more."

Neeleman, who was born in Brazil and spoke Portuguese at the news conference, said the Embraer 190s would be put to use on various existing routes. Moreover, it may open a route between Boston and New York.

"We never say where we're going to open a flight because of competition, but we have a big presence in Boston and in New York, so we will probably fly there," Neeleman said.

He added the price for round trip flight could be around USD$100, about a quarter of the current market price.

Embraer is marketing the 190 as a more cost effective airplane for regional and domestic air markets, which currently use larger planes by Boeing and Airbus or smaller planes that carry about 50 passengers.

Neeleman said the 190s could carry more passengers than the small jets and fly more times a day than larger airplanes.

The new 190s give JetBlue 1,000 new possible domestic routes, Neeleman said, although he did not say how many of those the airline would actually start to offer.
