Some excerpts from the article:
"So what's keeping JetBlue Airways from saying "I do" to Cincinnati?
For better or worse, the regional business community isn't ready to divorce Delta Air Lines, despite its massive downsizing here over the past decade. That's left JetBlue skittish about launching flights to Boston from Cincinnati/Northern Kentucky International (CVG), sources say, because the discount airline is fearful companies are still too loyal to Cincinnati's dominant carrier."
"... ... ...other cities hit hard by the downsizing of a dominant carrier have been able to bring JetBlue to town, including regions that compete with Cincinnati for jobs. JetBlue arrived in Cleveland this past spring, 15 months after United Airlines pulled the plug on its once-booming Northeast Ohio hub. It's still early for JetBlue in Cleveland, and the airline has encountered some turbulence after going into other dominant-carrier markets. In 2006, JetBlue launched four daily nonstop flights from Pittsburgh to New York City after US Airways pulled the plug on its Western Pennsylvania hub.
JetBlue later cut two of the flights, and in 2013 the carrier ceased all service to New York from Pittsburgh. Many companies had maintained corporate accounts with US Airways, according to the
Pittsburgh Post-Gazette."
"Business leaders and airport officials believe if American succeeds on the LaGuardia Airport flights, it will show JetBlue that Greater Cincinnati corporate fliers are willing to support other airlines. Aviation experts say we shouldn't read into American's decision too much, because it's part of the company's nationwide strategy to aggressively compete against Delta."
