JetBlue detailed what it called the first step in its Logan expansion plans with an increase of a total of 11 flights to 12 US cities starting May 1.
Besides its previously announced plans to resume flights between Boston and San Francisco with seasonal service, the discount carrier says it will add second daily flights to Charlotte, N.C.; Chicago O’Hare; Pittsburgh; and Raleigh/Durham, N.C.; a third flight to Buffalo, N.Y., and Long Beach, Calif.; sixth and seventh flights to Dulles; and a ninth and 10th flights to JFK.
JetBlue said in October that it was planning to increase its Logan presence.
Analysts have characterized the growth in Boston as very smart as it targets gaps left by other airlines, which either have dropped routes or are no longer serving them as well as they might.
Boston is already JetBlue's second-largest city, behind New York, and the carrier offers service to more destinations than any other at Logan.
Sebastian White, a JetBlue spokesman, said that he was not sure when the airline would disclose further expansion but expected that there would be more news in the first couple months of 2009.
