LE BOURGET, France — Airbus beat its rival Boeing in the orders stakes at the Paris Air Show, but both aircraft manufacturers were encouraged that their lucrative wide-body planes were finding new customers — a sign that the global economy could be on the mend.
The show at Le Bourget, which alternates with the Farnborough Air Show on an annual basis, is a platform for the sales race between the world’s two major aircraft makers, whose customers are increasingly interested in the new-generation, energy-efficient planes to offset huge jumps in jet fuel prices.
Though Europe’s Airbus said Thursday it had about $70 billion in sales at the show, it acknowledged a problem with its large backlog, which will delay the delivery of jets. Boeing Co., which last week signaled it expected a lower tally than Airbus, announced orders worth $66 billion — last year Boeing won the annual orders battle at Farnborough, south of London.
Each company tends to inflate its sales figures. Customers routinely negotiate enormous discounts — in at least one widely-publicized case, a markdown of more than 50 percent — the details are usually secret.
Though both companies announced a series of orders for their single-aisle jets, most interest at this year’s event was centered on sales of their bigger planes. Longer-haul aircraft cost a lot more and have been in less demand inthe past few years because of the tough global economic environment. But, along with a recovering global economy, there are signs that airliners are renewing fleets.
‘‘We continually keep underestimating how quickly Middle East, Far East, and indeed emerging markets are growing. We’re seeing a greater intensification of the mature nations realizing they have to invest in the future. That’s why the A350 is doing well. That’s why the 787 is doing well,’’ said Howard Wheeldon, an aerospace analyst.
The number of passenger planes in the air is expected to double in the next 15 to 20 years, according to industry figures, including those released last week from Boeing.
‘‘You’re not going to get into Charles de Gaulle 15 years from now with double the number of flights. We have to have larger aircraft,’’ said John Leahy, Airbus’ chief operating officer.
Airbus’ A350, which flew last week for the first time, gained 69 new orders — including upgrades from earlier orders for older jets — and the firm also secured sales for 20 of its biggest aircraft, the A380.
A big order came from United Airlines, which agreed Thursday to buy 10 A350-1000s, the largest version of the jet which typically seats 350 passengers. The carrier also converted a previous order for 25 A350-900s into -1000s. The new orders are worth $3.3 billion at list prices.
