Airbus raised its forecast for deliveries by 6 percent to 34,899 aircraft worth USD5.3 trillion over the next 20 years, creating jobs for more than a million pilots and technicians as China surges past the United States to dominate air travel. The number of people taking a plane is expected to triple over the same period as the size of the world's middle class doubles to 5 billion people. But Airbus trimmed its forecast for air traffic growth to 4.4 percent a year from 4.5 percent on June 9. Airbus said its forecasts contained more traffic and deliveries thanks to more tourism, liberalization, and a surge in private consumption. The world's second largest plane maker after Boeing also predicted a surge in repairs, training, and upgrade work for manufacturers as the world's fleet tops 40,000 jets by 2036. This means hundreds of thousands of new jobs, and an estimated need for 530,000 more pilots and 550,000 new maintenance engineers.
