About the Boeing 737-700

The Boeing 737 is the best-selling commercial jetliner in history and the backbone of short-to-medium-haul aviation worldwide. First flown in 1967 as a smaller companion to the 727, the 737 has evolved through four major generations (Original, Classic, Next Generation, and MAX), with over 11,000 delivered across all variants. Its enduring success stems from exceptional economics, commonality across the family that simplifies crew training and maintenance, and the flexibility to serve routes from 300 to 3,500 nautical miles with 100 to 230 passengers depending on variant.

The Next Generation 737 (737-600/700/800/900), introduced in the 1990s, became the workhorse of low-cost carriers and legacy airlines alike, featuring CFM56 engines, a glass cockpit, and blended winglets that improved fuel efficiency by up to 5 percent. The 737-800, the most popular NG variant, cruises at Mach 0.785 and can reach 41,000 feet, offering range up to 3,115 nautical miles, enough to connect most city pairs within a continent or cross the Atlantic on thinner routes. Its approach speed of roughly 138 knots and maximum operating speed of 340 knots IAS (or Mach 0.82, whichever is lower) reflect a design optimized for rapid turnarounds and high daily utilization, with some aircraft flying eight or more sectors per day.

The type's ubiquity means parts, mechanics, and pilots are available at nearly every major airport, a logistical advantage no competitor has matched. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
