SINGAPORE (Reuters) - 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 told Reuters in a statement.

“Nothing different applies for our Singapore Airlines Suites customers.”

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

Singapore Airlines, the world’s second-largest airline by market value, started commercial flights of the double-decker A380 last week with a Singapore-Sydney service.

“So they’ll sell you a double bed, and give you privacy and endless champagne and then say you can’t do what comes naturally?” Tony Elwood, who traveled with wife Julie in a suite aboard the inaugural flight, told the Times of London.

“They seem to have done everything they can to make it romantic, short of bringing round oysters,” Julie said. “I’d say they shouldn’t really complain, should they?”
