Qatar Airways shows no sign of slowing down in terms of innovation. Earlier this week in ITB Berlin -- the world's largest travel trade show -- the carrier unveiled their all-new QSuite, a new service set to be installed in business class.

Basically, the QSuite will allow passengers on business class to enjoy a double bed cabin. By reclining two middle seats into a fully flat bed, complete with partition panels and two entertainment screens, guests can enjoy their own private bedroom.

A first in business class, it's surely a new standard set by Qatar Airways in terms of innovation of service. Determined to exceed even the first-class service of many of its rivals, the QSuite will be the start of the upgrade.

But that's not all. Four private suites can be conjoined into a private communal space for groups of passengers traveling together. These suites come with adjustable panels and movable TV monitors so that it could be stowed away when needed. This way, a group can enjoy the flight within their own private space by dining and socializing together.

Other perks and features include hand-stitched Italian leather and satin rose gold seats, amenity kits designed by luggage brand Bric's, upgrade of 3,000 contents of the Oryx One in-flight entertainment system, and expanded dining options.

For passengers flying in the night-time, they would automatically receive a complimentary set of pajamas from the luxurious brand, The White Company. According to reports, a return flight from London to Doha, Qatar will cost around $4,600.

The QSuites will be installed in Qatar Airways' existing aircrafts starting this June with a rate of one suite installation in one plane a month. With the amount of existing aircrafts Qatar Airways have, it might be a little while before all will be retro-fitted, but the premier airline company guaranteed customers that it's well worth the wait.

In a statement made by airline's group chief executive, His Excellency Mr. Akbar Al Baker, he said: "Our unique and patented design is a world first in many ways and challenges industry norms by offering passengers more privacy, more choice and more personalisation."

"With these innovations, Qatar Airways has revolutionized the way we serve our business class travellers enabling our passengers to enjoy a first class experience in business class," he added.
