London, Nov 1 : Singapore Airlines’ new Airbus A380 boasts of having the world's first airborne double beds, but the luxury comes with a warning for some randy couples – No sex please!

Many romantic couples’ hopes of joining the mile-high club were shattered by the airline after it announced that it would ask passengers to refrain from sex while travelling in one of its 12 first-class suites.

The warning comes after passengers discovered that the super jumbos' 12 private suites are not soundproof.

The airline said it doesn’t want the romping sessions to offend other travellers or crew anywhere within the plane.

"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 Sun quoted the company, as stating.

"Nothing different applies for our Singapore Airlines Suites customers,” the company added.

However, some passengers are not convinced with the company’s “no sex” warning.

"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 travelled with wife Julie in a suite aboard the inaugural flight, told The Times.

Singapore Airlines is the first operator to use the new planes, flying between Singapore and Sydney from October 25. (ANI)
