An internal email from JetBlue outlines some of the basics of the free wi-fi plan. "Currently, wi-fi on board is a competitive advantage," according to the letter. "Customers, especially those traveling for business, with everything else being equal, will choose the airline that offers connectivity, even if the service is spotty or expensive....The challenge for us was building a wi-fi product that broke this slow, frustrating and ultimately unsatisfactory mold. We wanted to find a way to deliver faster and less expensive service that would result in greater satisfaction. With LiveTV partnering with ViaSat, I think we found the sweet spot." It would be free service "until the first 30 aircraft are equipped with our service," said the note.
