Southwest Airlines is now flying new routes and more flights from several major airports, including New York LaGuardia, Washington Reagan National and San Jose, California.

Many of the expanded services, first announced in May, began flying Sunday as Southwest rolls out updates to its fall and winter schedules.

Among the highlights are new destinations and increased frequencies from LaGuardia and Reagan National, two capacity-controlled Northeast airports popular with business travelers in those cities. Flights are capped at each, but Southwest was able to expand after securing slots from Alaska Airlines, which shed some of its New York and D.C. flights that it inherited in its acquisition of Virgin America.

Southwest's new routes from LaGuardia include nonstop service to New Orleans as well as two upcoming weekend-only routes to Florida that begin next weekend. From Reagan National, Southwest is adding nonstop service to Oklahoma City. The carrier will also add more flights to existing destinations from each airport.

In California, Southwest is expanding its footprint at the San Jose and Burbank airports, both with new destinations and an increase in flights on existing routes.

However, one nonstop route was axed in the update. The airline’s flights between Portland, Oregon, and Orange County, California, ended Saturday (Nov. 3), though Southwest still offers connecting itineraries between the airports.
