The first Boeing Next-Generation 737-700ER takes off for a test flight from Boeing Field prior to its delivery today to launch customer ANA (All Nippon Airways). ANA will begin operations with the airplane in March with its new ANA BusinessJet service, providing international business travelers with 24 business class and 24 premium economy class seats, both in four-across configuration. The 737-700ER is inspired by the Boeing Business Jet and is designed for long-range commercial applications.
