For JetBlue Airways, Boston is becoming big business.
In the six years since it entered the market, the low-cost carrier has become the largest airline at Logan International Airport, pushing down fares and helping to reverse a decade-long slide in passenger numbers. While other airlines have pared down operations in Boston in recent years, JetBlue has made the city a cornerstone of its growth strategy, pitting it against low-fare rival Southwest Airlines, which started flying from Logan last year.
“We saw people driving to Providence and Manchester to fly Southwest and knew there was a strong customer base,’’ said Marty St. George, JetBlue’s senior vice president of marketing and commercial strategy, adding that at Logan, the airline saw an opportunity to build a leading position at one of the only major US airports without a dominant competitor. “For years, you’ve had three high-fare airlines splitting Boston, none of them making a major commitment to the market.’’
