FedEx, the express freight group, has delivered a vote of confidence in Airbus's troubled A380 superjumbo, saying it remains committed to the aircraft and expects its order to be completed on schedule.

Fred Smith, chairman and chief executive, said, while the latest delays to the A380 were "a source of concern", FedEx had been assured its 10 aircraft would not be affected. "We're confident," he told the FT. "They have told us that ours are going to arrive on time."
