TAT Group subsidiary Aircraft International Renting placed an order for two 70-seat ATR 72-500s for delivery late this year and next to Bangkok Airways. Order is valued at $37 million at list prices and will bring the airline's -500 fleet to 20.

TNT will invest €100 million ($157.9 million) over the next five years to expand its Europe-Asia express cargo services.

Bangalore-based National Aerospace Laboratories will receive approximately $75 million from India's Council of Scientific and Industrial Research to launch design of a turboprop aircraft to rival those manufactured by ATR, Mint business daily reported. The RTA 70 project eventually will cost an estimated INR20 billion ($500.6 million) and will aim at flying a 70-seat prototype aircraft in four years, project head Kota Harinarayana told the paper. It also expects to design 50- and 90-seat models. Harinarayana said the aircraft will have more composites than current models.

US major airlines will need to spend an estimated $110 billion to update their fleets, but even if they had the money, which they don't, the order backlog at Airbus and Boeing "means any replacements are years from delivery," according to a report from UK-based Ascend.
