Delta Air Lines is adding 12 new daily flights to 11 domestic and Caribbean destinations from New York JFK and New York LaGuardia in spring and summer 2012.

In March, Delta Air Lines will add new frequencies between New York JFK and Santo Domingo and Santiago de los Caballeros in the Dominican Republic; and between New York JFK and San Juan, Puerto Rico.

Delta also will launch new nonstop service between New York LaGuardia Airport and Nassau in The Bahamas. The new and expanded Caribbean routes will serve significant local demand for flights to those markets, according to the airline.

In addition, Delta will add new routes and frequencies in June to seven U.S. cities from New York JFK. The cities include Austin, Texas; Jacksonville, Florida; Kansas City, Missouri; New Orleans; Milwaukee; San Francisco; and Los Angeles.

The world's second-largest airline as a result of its merger with Northwest Airlines in 2009, Delta Air Lines operates a massive fleet which includes many different aircraft types. Among the types Delta operates is the Boeing 737-800, of which the carrier operates 73. Delta also operates 10 Boeing 737-700s and ordered 100 Boeing 737-900ERs in 2011

With a new daily flight in each city, Delta will offer a total of eight peak-day flights to Los Angeles and six peak-day flights to San Francisco from New York JFK.

“Our expanded service to these key Caribbean and domestic destinations reinforces our ongoing commitment to our customers in New York,” says Gail Grimmett, Delta’s senior vice president – New York. “With our planned expansion at LaGuardia Airport, and our terminal renovation and expansion at JFK, Delta is continuing to position itself as the preferred carrier for customers traveling to and from New York.”

All flights will be operated with aircraft fitted with two-class cabin configurations. Tickets are available for sale at and other ticketing outlets. Schedule details for Delta’s new flights are available at

Delta Air Lines is building an expanded concourse as part of a $1.2 billion project to enhance Terminal 4 at John F. Kennedy International Airport, with Delta’s big new terminal area due to open in 2013.

The carrier also recently received approval from the U.S. Department of Transportation for a slot transfer with US Airways which Delta says will allow it to double the number of nonstop destinations it serves from LaGuardia, adding as many as 4 million additional round-trip seats from LaGuardia without increasing congestion.

Delta plans to invest $100 million creating an expanded main terminal at LaGuardia, with a new 600-foot connector bridge between terminals D and C.
