Boeing delivered the first 747-8 Intercontinental Tuesday to an unidentified client, but the latest and biggest version of its jumbo jet is hardly ready for its mysterious owner: Completing the interior will take until 2014.

The VIP version of the 747-8 Intercontinental has a 4,786-square-foot cabin. In addition, the plane will be outfitted with a so-called Aeroloft from Kirkland-based Greenpoint Technologies — a nearly 400-square-foot private sleeping area above the main passenger deck in the rear portion of the aircraft.

The interior will be installed in Wichita, Kan., by Boeing's Global Transport and Executive Systems unit.

Boeing said this 747-8 Intercontinental is configured to carry 100 passengers and has a range of about 8,840 nautical miles.

Some reports have said the initial customer is the royal family of Kuwait. The ruling families of Qatar and the United Arab Emirates also have bought early models.

The freighter version of the 747-8 entered service late last year.

Boeing said the first 747-8 Intercontinental for airline use will finish flight testing for certification for service within a week.

The first plane will be delivered to Germany's Deutsche Lufthansa in the "very near future," Elizabeth Lund, the 747 program manager, said Tuesday at a ceremony in Everett.
