Boeing 737-700

73G B737 Out of Production

A mid-size member of the Boeing 737 Next Generation family, the 737-700 seats about 126 passengers in two classes and up to 149 single-class. Two CFM56-7B24 turbofans give it a range near 6,230 km at a cruise of 834 km/h. First flown in 1997, the aircraft is 33.6 metres long with a 34.3-metre wingspan and a maximum takeoff weight of 70,080 kg. Balancing range, capacity, and cost for high-frequency short-haul flying, the -700 served for years as the signature aircraft of Southwest Airlines, whose large single-type fleet built much of its network around the variant.

About Boeing 737-700

Popular mid-size member of the 737 NG family. Southwest Airlines' signature aircraft, the -700 balanced range, capacity, and operating costs for high-frequency short-haul operations.

Frequently Asked Questions

The Boeing 737-700 typically seats 126 passengers in a two-class configuration. Southwest Airlines, the largest operator, configures its 737-700s with 143 seats in an all-economy layout. The aircraft is 33.6 m long, making it the shortest member of the 737 Next Generation family.

The Boeing 737-700 has a maximum range of approximately 6,230 km (3,365 nautical miles). This allows it to cover routes like Dallas to Anchorage, London to the Azores, or Tokyo to Manila. The BBJ (Boeing Business Jet) variant based on the 737-700 airframe can fly up to 10,200 km with auxiliary fuel tanks.

The 737-700 and A319 are close competitors with similar passenger capacity (126 vs 124 seats). The A319 has a wider cabin and longer range by about 620 km. However, the 737-700 has lower maintenance costs for airlines already operating other 737 variants due to fleet commonality. Southwest Airlines has been the dominant 737-700 customer with over 500 aircraft in its fleet.

The 737-700 shares the same blended winglets, CFM56-7B engines, and nose shape as the 737-800, but has a noticeably shorter fuselage. It has only one overwing emergency exit per side compared to two on the 737-800. If seen near a 737-800, the length difference of about 6 meters is clearly visible in the shorter cabin section aft of the wing.

Production of the 737-700 has effectively ended, with the 737 MAX 7 designated as its replacement. Southwest Airlines was the largest 737-700 customer and has been gradually transitioning to the 737 MAX 8. The 737 MAX 7, which offers better fuel efficiency and range, has faced delays in certification. Many 737-700s will remain in service through the early 2030s with existing operators.
