An Airbus A320neo takes off for its first test flight

 Upstart Brazilian airline Azul, run by US-Brazilian entrepreneur David Neeleman, is buying 35 fuel-efficient mid-range A320neo planes to expand its operations, according to manufacturer Airbus.
The deal is nominally worth 2.9 billion euros ($3.6 billion) at Airbus's catalogue prices, though discounts are routinely given. Azul has separately already ordered 28 other A320neos through a leasing contract.
