Southwest Airlines announced a host of new travel options Monday, including the as-promised plans for expanding into New York’s LaGuardia Airport.

The airline opened booking up through June 2014 and announced increased service between LaGuardia and Nashville, Houston, Chicago Midway and Akron-Canton, Ohio. The new service begins May 11, 2014 and is the result of the reallocation of slots as part of the American Airlines-U.S. Airways merger agreement with the U.S. Department of Justice.

Southwest Airlines also announced new nonstop service out of San Diego to Orlando, New Orleans, Portland, Ore. and Seattle/Tacoma. The new flights come as Southwest gets ready to celebrate its 32nd anniversary of serving San Diego's Lindbergh Field.

The airline also is beefing up in Portland, Ore., by offering new nonstop destinations to customers in the northwest. That includes the two daily nonstop flights to San Diego, as well as daily service to Baltimore/Washington, Chicago (Midway), and Houston Hobby.

As Southwest moves toward its final phase of integrating AirTran Airways, new nonstop service at Hartsfield-Jackson Atlanta International Airport includes service to Detroit, Minneapolis/St. Paul,Milwaukee, and Pittsburgh.
