Delta Air Lines (Atlanta) has unveiled plans for the complete revitalization of its fleet of Boeing 747-400 aircraft flying primarily from the Tokyo-Narita hub. Between summer 2011 and 2012, Delta will equip each of its 16 747-400s with new fully horizontal flat-bed seats in the BusinessElite cabin and new Economy class seats featuring personal, on-demand entertainment, increased personal space and added under-seat storage.

The 747 upgrades will bring substantial changes to both decks of the aircraft’s BusinessElite cabin. The new, custom-designed product will feature 48 horizontal flat-bed seats with direct aisle access at each seat. Window seats will face the window for improved privacy and center seats will be angled toward each other for the convenience of customers traveling together.

The new seat, manufactured by Weber Aircraft LLC, will be 81.7 inches in length and 20.5 inches wide, similar to the flat-bed product currently offered on Delta’s 777-200LR fleet. It also will feature a 120-volt universal power outlet, USB port, personal LED reading lamp and Panasonic’s 15.4 inch personal video monitors with instant access to 250 new and classic movies, premium programming from HBO and Showtime, video games and more than 4,000 digital music tracks.

Customers in Economy class on the 747-400 will benefit from the industry’s first seat designed collaboratively by a seat manufacturer and an in-flight entertainment company, Weber Aircraft and Panasonic Avionics Corporation, to fully incorporate seat and entertainment functionality into one product. Using a nine-inch screen, the new seat’s embedded touch-screen entertainment system will offer each customer access to 250 movie titles, hundreds of television shows, 4,000 digital music tracks, personalized music playlists, more than a dozen interactive games and a USB port to charge iPods and other personal electronic devices.

The new seats offer up to 1.5 inches more personal space and increased under-seat storage through a “slimline” design that more efficiently uses cabin space than the older, heavier seats they replace. The upgraded seats also feature adjustable headrests and deliver environmental benefits through the Panasonic Eco 9i Integrated Smart Monitors that use 30 percent less energy and are 60 percent lighter than entertainment systems installed on other Delta aircraft.

Delta’s 747s are dedicated largely to trans-Pacific and intra-Asia flights to and from the Tokyo-Narita hub, including routes connecting Tokyo to Detroit, Honolulu, Manila, Minneapolis/St. Paul, New York-JFK and Shanghai.

When reconfigured, the 747s will accommodate 386 customers with 48 BusinessElite seats and 338 Economy class seats.
