LE BOURGET, France: There was a headlong rush of major aircraft orders on the second day of the Paris International Airshow Tuesday as rivals Airbus and Boeing fought to grab the headlines. The day was dominated by the Airbus A320neo, the upgraded, more fuel-efficient medium-haul workhorse which appeared to get the better of Boeing's venerable 737 series, the world's biggest-selling plane. The medium-haul market is the single most important segment of the industry and will likely account for nearly half of all commercial aircraft sales by value over the next 20 years, according to Boeing. The figures do not include memorandums of understanding or letters of intent for aircraft of which there were several Tuesday, mostly large potential orders for the Airbus A320neo. Airbus: q 60 A320neo aircraft, the updated and more efficient version of the workhorse A320 series, worth some $5.5 billion dollars at list price for Gecas leasing company of the United States. q 36 A320neos plus 14 options for Aircraft Leasing Corporation which also ordered one A321 and 11 long-haul A330s in a deal that could be worth $6.0 billion. q 30 A320neos for Scandinavia's SAS Airlines, worth up to $2.8 billion. q 6 A320neos for Taiwan's TransAsia worth $600 million. q Four A330-300s for Saudi Arabian Airlines, worth $800 million. Boeing: q 14 B737-800s worth $1.1 billion for Aircraft Leasing Corporation. q Two B747-8, the upgraded version of the original 747 jumbo jet aimed at the Airbus A380 superjumbo, with a list price of $635 million.

Bombardier: q 10 CS100 regional jets worth more than $600 million. q 10 Global 8000 business jets for Switzerland's VistaJet, a business aviation specialist, worth $650 million ATR, a joint venture of EADS and Italy's Alenia: The company said it had 78 total orders worth $2.4 billion in all among which it detailed: q 15 ATR 72-600 planes for leasing company GECAS worth some $340 million. q 10 ATR 72-600 for Brazil's Azul. Airbus benefited from airlines' worries about sky-high fuel prices, winning customers for scores of its more fuel-efficient planes. Airbus sought to focus attention on its order books after it suffered a clipped wing, faulty gearbox and delays to a new jet ahead of the aviation industry's showcase event. The star of this year's air show so far is a plane that won't be airborne until at least 2015: the Airbus A320neo. It is a revamped version of the workhorse A320 family of single-aisle short and medium haul aircraft, but with more fuel-efficient engines. As oil prices have jumped higher this year, the plane has become the company's fastest selling model.
