PARIS, Nov 7 (Reuters) - Europe's Airbus extendedits lead over Boeing in a hard-fought order contest in October,but remained behind on deliveries, leaving its U.S. rival in theindustry's no.1 spot.
Airbus said it had sold 153 jets in the month to bring neworders for the first 10 months of the year to 1,265 aircraft.
Boeing's orders for the same period stood at 1,102jets, the company said in a monthly breakdown on Thursday.
October was dominated by high-profile defections of twoairlines previously loyal to Boeing as Mexican airlineVivaAerobus and Japan Airlines opted for Airbus jets.
Boeing, which won the race on both orders and deliveries in2012, is expected to hit back with significant sales at thismonth's Dubai Airshow but analysts say Airbus has the edge inthis year's order battle while trailing behind on deliveries.
After cancellations, Airbus booked a total of 1,215 netorders from January to October, up 14 percent from the sameperiod a year earlier and well above Boeing's 957 net orders.
Airbus had already exceeded its official target of 1,000gross orders by the end of September, but by breaking throughthe 1,200 barrier it has also beaten an internal goal.
Airbus continued, however, to show a blank scorecard for2013 sales of the A380 superjumbo. Disappointing sales of theworld's largest aircraft have raised questions over productionand ambitions to break even on the jet in 2015.
Parent EADS is expected to update investors on targets withquarterly results on Nov. 14.
Airbus delivered a total of 504 planes between January andOctober including four A380s that brought total superjumbodeliveries this year to 18, against a full-year target of 25.
Boeing delivered 530 aircraft in the same period and lastweek announced plans to increase production targets from 2017 tomeet strong demand for medium-haul jets.
The latest industry data comes as Boeing prepares to unveilpotentially record orders for its new 777X wide-body jet at theNov. 17-21 Dubai Airshow, subject to board approval.
Industry sources say a decision on whether to launch theplane with what some estimate to be as many as 250 potentialorders, including deals outside the Gulf, hinges on union andlegislature approval for proposals to build the plane in theSeattle area in return for labour and tax concessions.
Airbus is also negotiating to sell aircraft at the MiddleEast aerospace event and is expected to close a deal for 20A380s with leasing company Doric Lease Corp soon.
Boeing's first data for early November meanwhile suggestedthat unidentified airlines had upgraded orders for 26 of thecompany's best-selling 737 jets to the newer MAX model.Southwest Airlines confirmed it accounted for 20 of these.
Demand for the fuel-saving 737 MAX and the competing AirbusA320ne, as airlines try to cut operating costs, has propelledcommercial aerospace through an unusually strong and prolongedupward cycle despite the financial crisis in developed markets.
