Spring Airlines Japan (IJ, Tokyo Narita) has seen its sole aircraft, a factory-fresh B737-800, JA01GR (msn 39429), ferried from Marana, where it had been in storage for three months, to Sapporo Chitose. It is presumed the aircraft will now be undergoing proving flights for the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) as part of the airline's efforts to obtain an Air Operators Certificate.
