737-800 is a member of the Boeing 737 Next Generation family produced by Boeing Commercial Airplanes. It serves as a medium-range, single-aisle airliner widely used by major carriers including American Airlines, Ryanair, United Airlines, Southwest Airlines, and China Southern Airlines. The type has influenced fleet strategies at airlines such as Lufthansa, Air France, British Airways, Qantas, and KLM and has been evaluated in markets alongside the Airbus A320 family and Embraer E-Jets.

Development and Design

Boeing developed the aircraft during an upgrade program that produced the 737 Next Generation family, with design work referencing projects at Boeing Wichita, Boeing Renton and involving suppliers such as CFM International, Honeywell, and Hamilton Sundstrand. The project drew on earlier collaborations with NASA research into aerodynamics and noise reduction and followed industry trends set by the Airbus A320neo development and decisions by carriers like Southwest Airlines and Delta Air Lines. The design incorporated advances from studies at Massachusetts Institute of Technology and University of Washington wind-tunnel testing, and certification processes administered by the Federal Aviation Administration and European Union Aviation Safety Agency.

The type spawned multiple customer-specific configurations and stretch/retrofit options installed by firms such as ST Aerospace, Lufthansa Technik, and Gulfstream Aerospace subcontractors. Major conversions included freighter adaptations by AerSale and passenger-to-freighter programs influenced by orders from UPS Airlines and FedEx Express. Airlines executed cabin retrofits using interiors from Collins Aerospace, B/E Aerospace, and Thales Group to meet ANA, Iberia, and Singapore Airlines service concepts. Performance and range mods referenced by operators paralleled studies by Pratt & Whitney and Rolls-Royce affinity programs.

The type entered service following certification flights overseen by the FAA and operational evaluations by launch customers among carriers like Hawaiian Airlines and Alaska Airlines. It has featured in route networks for legacy and low-cost carriers, influencing market competition with Ryanair, easyJet, JetBlue Airways, and Spirit Airlines. Government and charter operators including Royal Air Force contractors and United States Air Force logistics units have used the airframe for transport and training roles. Fleet deployment considerations referenced capacity decisions at John F. Kennedy International Airport, Heathrow Airport, Shanghai Pudong International Airport, and Dubai International Airport.

The model is powered by CFM International CFM56 turbofan engines with avionics suites provided by Collins Aerospace and Rockwell Collins systems, integrating flight management from Honeywell and navigation tied to Global Positioning System constellations. Structural components were produced in coordination with suppliers including Spirit AeroSystems, Goodrich Corporation, and Messier-Bugatti-Dowty for landing gear. Its systems compliance involved standards from the Federal Aviation Administration and European Union Aviation Safety Agency certification regimes and drew upon computational fluid dynamics work from Stanford University and University of Cambridge research groups. Performance metrics were benchmarked against the Airbus A321 and tested during scenarios outlined in ICAO and International Air Transport Association guidance.

Major operators have included Southwest Airlines, which managed a large NG fleet strategy, as well as Ryanair, which ordered significant quantities as a backbone of its route density model. Legacy carriers such as American Airlines, United Airlines, Delta Air Lines, and British Airways employed the type for domestic and short-haul international services. Lease companies such as AerCap, Avolon, and GE Capital Aviation Services facilitated global distribution to carriers in regions including Latin America, Africa, Europe, and Asia Pacific. Government procurement and military leasing involved agencies such as U.S. Department of Defense contractors and civil registries at authorities like the Civil Aviation Administration of China.

The aircraft's operational record has been analyzed in safety reviews conducted by the National Transportation Safety Board and European Union Aviation Safety Agency investigations following incidents involving airlines such as Gol Transportes Aéreos and LOT Polish Airlines. Accident investigations frequently cite factors assessed by Boeing engineering teams, airworthiness directives issued by the FAA, and recommendations from Flight Safety Foundation and International Civil Aviation Organization. Safety modifications and maintenance programs have been implemented by carriers in cooperation with Airworthiness Directive issuances and major maintenance organizations like Lufthansa Technik and SR Technics.
