JetBlue to add premium seats on some flights - Businessweek
JetBlue's chief commercial officer, Robin Hayes, said JetBlue's transcontinental service is producing weaker financial results than other flights because of the lack of premium seats and Wi-Fi Internet access. Passengers will live without Wi-Fi on a short flight, but "they do not want to fly five, six hours across the country and not feel connected," he said.
