The flight from Frankfurt to San Francisco highlighted the A340-600's smooth cruising qualities. The aircraft took off from Frankfurt at 344 tonnes, performed a brisk climb to flight level 340, gradually reaching level 410, and flew the entire sector at Mach 0.84. Passengers, including press, airline and Airbus technical staff, as well as a group of Lufthansa frequent flyers, described the plane as extremely stable, notably at the back of the plane. The A340-600 has now left San Francisco for Montreal, where guests from launch customer Air Canada are expected.
