Singapore Airlines, the first operator of the new Airbus A380, has dashed the hopes of sexual thrill-seekers planning to engage in amorous activity aboard the world's biggest jumbo jet.

The carrier said it would ask passengers on the A380 to refrain from sex while ensconced in one of its 12 first-class suites, which boast the world's first airborne double beds.

"All we ask of customers, wherever they are on our aircraft, is to observe standards that don't cause offence to other customers and crew," the company said in a statement. . . .

While private, the double cabins are neither sound proofed nor completely sealed.
