Boeing 747-8 flight

The 747-8 Intercontinental is the only jetliner in the 400- to 500-seat market, stretched 5.6 m (18.3 ft) from the 747-400 to provide 467 seats in a three-class configuration and a 14,815-km (8,000-nmi) range. Using 787-technology engines, the airplane will be quieter, produce lower emissions, and achieve better fuel economy than any competing jetliner. The 747 Intercontinental will provide nearly equivalent trip costs and 13 percent lower seat-mile costs than the 747-400, plus 26 percent greater cargo volume. Operating economics will offer a significant improvement over the A380. The 747-8 is more than 10 percent lighter per seat than the A380 and will consume 11 percent less fuel per passenger than the 555-seat airplane. That translates into a trip-cost reduction of 21 percent and a seat-mile cost reduction of more than 6 percent, compared to the A380. Both the 747-8 Intercontinental and 747-8 Freighter can use the existing infrastructure and ground equipment at most airports worldwide.
The 747-8 Freighter will be longer than the 747-400F by 5.6 m (18.3 ft) and have a maximum structural payload capability of 140 metric tonnes (154 tons) with a range of 8,130 km (4,390 nmi). Also powered by 787-technology engines, it will achieve the same environmental benefits as the 747-8 Intercontinental. The 747-8 Freighter will have nearly equivalent trip costs and 16 percent lower ton-mile costs than the 747-400, plus 16 percent more revenue cargo volume than its predecessor. The additional 120 cu m (4,245 cu ft) of volume means the airplane can accommodate four additional main-deck pallets and three additional lower-hold pallets. Operating economics of the 747-8 Freighter will be significantly superior to the A380F. The 747-8F's empty weight is 80 tonnes (88 tons) lighter than the A380F, resulting in a 24 percent lower fuel burn per ton, 21 percent lower trip costs and 23 percent lower ton-mile costs than the A380F.
