Frontier Airlines’ expanded Madison service takes to the skies with the launch of year-round nonstop service to Orlando International Airport on June 3 and daily nonstop service to Washington, D.C. Reagan on June 7.

The Orlando service moves from seasonal to year-round and includes an aircraft upgrade. The D.C. service increases from three times weekly to daily with a significantly improved flight schedule.

"The Madison community is doing a great job of supporting Frontier, so we’re happy to keep adding nonstop service -- now daily to both Washington, D.C. and Denver and year-round to Orlando," said Daniel Shurz, Frontier’s senior vice president, in a news release. "We’re looking forward to seeing even more residents of the Madison area taking advantage of the great travel values offered at FrontierAirlines.com."

The Dane County Regional Airport has announced that Delta Air Lines will be upgrading existing service from Madison beginning July 11. 

Starting on July 11, several flights from Madison will be upgraded to two-class aircraft, eliminating many 50-seat, single-class regional jets, officials said.

Routes that will be affected include flights to Detroit, Atlanta and Minneapolis. 

Some of the features passengers will benefit from include in-flight Internet access, power outlets and USB connections. 

"We are extremely pleased that Delta has decided to upgrade these aircraft for our customers traveling to and from Madison," said Airport Director Bradley Livingston in a news release. "Two-class service is important to our business and leisure travelers, and Delta responded with these equipment changes."

In addition, DCRA marked a surge in passenger traffic February, with a 17 percent increase compared to 2011.
