Local transportation options are expanding this summer, with an additional flight to Baltimore from the Portland International Jetport and a second round-trip bus service between Ogunquit and New York City beginning next month.

Southwest Airlines has added a fourth daily round trip to Thurgood Marshall International Airport in Baltimore. The flight will operate through Nov. 4.

The additional flight will leave Portland at 9 a.m., arriving in Baltimore at 10:25 a.m., and the return flight will leave Baltimore at 8:20 p.m. and arrive in Portland at 9:50 p.m. Southwest added a fourth daily flight last year, but ended the service on Labor Day.

“That two extra months of flying is almost 9,000 additional seats in market,” said Zach Sundquist, assistant airport director, in a release announcing the service. Airport officials cited increased interest in Maine’s fall foliage as a reason Southwest chose to extend the season for the fourth flight.

Portsmouth-based C&J Bus Lines said it will add another round trip between Ogunquit and New York City starting May 20 to meet growing demand for more summer travel.

The second trip will operate Thursday through Monday, leaving from the Ogunquit Chamber of Commerce building on Route 1, heading to the Port Authority bus terminal in New York City.

Departures will be at 8:45 a.m. and 1:45 p.m. with arrival in NYC about six hours later. Prices are $85 each way.

C&J currently offers a round trip between Ogunquit and New York seven days a week from Memorial Day to Labor Day. After Labor Day, C&J will continue to offer weekend service to Ogunquit through Columbus Day.

The company transports passengers aboard a 30-passenger executive-class bus, which has leather seats, power outlets, WiFi, tray tables, movies and a full self-service refreshment galley. Newspapers, headsets, pillows and blankets are also available.
