Travellers may to have to wait until 2007 to fly in the world's biggest passenger plane after manufacturers Airbus announced delivery delays of up to six months. The first of the part British-made 555-passenger Airbus A380 superjumbos was to have been received by Singapore Airlines in the period April-June 2006. But Singapore said today it was now not getting the first delivery until the last part of 2006. The airline had hoped to make the first A380 commercial flight around the middle of next year, but that date could now slip into 2007. A Singapore Airlines' spokesman said today: "It's still possible we can have the inaugural flight in 2006, but all the necessary tests will have to be conducted." Toulouse-based Airbus, in which UK aerospace company, BAE Systems, has a 20% stake and whose planes' wings, including those of the A380, are built by Airbus UK in Broughton, north Wales, first revealed the double-decker superjumbo at a lavish ceremony in January this year.
