ABOUT
In November 1993, Southwest Airlines launched the Next-Generation program with an order for 63 737-700s and took delivery of the first one in December 1997.[1] It replaced the 737-300, typically seating 126 passengers in two classes to 149 in all-economy configuration, similar to the Airbus A319.

In long-range cruise, it burns 4,440 lb (2,010 kg) per hour at Mach 0.785 (450 kn; 834 km/h) and FL410, increasing to 4,620–4,752 lb (2,096–2,155 kg) at Mach 0.80 – Mach 0.82 (459–470 kn; 850–871 km/h).[46] As of July 2018, all -700 series on order, 1,128 -700, 120 -700 BBJ, 20 -700C, and 14 -700W aircraft, have been delivered.[3] By June 2018, around one thousand were in service: half of them with Southwest Airlines, followed by Westjet with 56 and United Airlines with 39. The value of a new -700 stayed around $35 million from 2008 to 2018. A 2003 aircraft was valued for $15.5 million in 2016 and $12 million in 2018 and will be scrapped for $6 million by 2023.
