It's official: JetBlue is returning to Atlanta after an absence of more than 13 years.

JetBlue will begin flying from Atlanta on March 30, when it begins flying five daily round-trip flights to its hub in Boston on Airbus A320 aircraft. The carrier said it also "intends" to add additional service from Atlanta to its bases at New York JFK, Fort Lauderdale and Orlando, though JetBlue did not specify a schedule or start date for those routes.

In announcing its return to Atlanta, JetBlue put the focus on its hub in Boston, wher it already is the biggest carrier. The airline said it's kicking off an effort to grow its schedule there "by more than 40% to 200 peak day departures." JetBlue currently offers about 140 daily departures on its busiest days at Boston.

Atlanta will be JetBlue's 63rd nonstop destination from Boston, and the carrier also revealed plans to expand existing service on three other routes from Boston.

"Boston travelers have spoken, and we are listening by adding Atlanta to our route map and expanding our operation to 200 peak day departures," Marty St. George, JetBlue's commercial and planning, chief, says in a statement. "After decades of being underserved by high-fare legacy carriers, Boston has an airline that is committed to offering the best service and most nonstop destinations of any other airline."

JetBlue also appears to be taking a tougher tone against its biggest rivals. In addition to St. George's comments about "high-fare legacy carriers" in Boston, JetBlue pledged its new Atlanta flights "would bring low fares and award-winning service (to) a city that is dominated by two of the Big Four airlines."

Delta is by far the dominant carrier in Atlanta. Southwest became the No. 2 carrier in Atlanta following its acquisition of AirTran, which had operated a large connecting hub there.
