Boeing 737-800

role : jet airliner

importance : ****

first flight : 31 July 1997 operational : April 1998 (D-AHFC Hapag Lloyd)

country : United States of America

ICAO aircraft type designator : B738

production : 4989 737-800’s at Renton

general information :

September 1994 final decision to build the 737-800. At that time, 4 airlines had ordered 40 aircraft. The -800 is based on the -400 but has been extended by 2.79m. It was initially referred to as -400X. It is the heaviest 737 and can carry 160 passengers over 5380km. In November 1995, Transavia ordered 8 aircraft with options for 12 more, worth 460 million NLG.

The 737-800 burns 850 US gallons (3,200 L) of jet fuel per hour—about 80 percent of the fuel used by an MD-80 on a comparable flight, while carrying more passengers. The Airline Monitor, an industry publication, quotes a 737-800 fuel burn of 4.88 US gal (18.5 L) per seat per hour, compared to 5.13 US gal (19.4 L) for the A320..

In early 2017, a new 737-800 was valued at $48.3 million, falling to below $47 million by mid-2018. By 2025, a 17-year-old 737-800W will be worth $9.5 million and leased for $140,000 per month. The 737-800 is the best selling 737NG variant and is the most widely used narrow-body aircraft.
