How many 737-200 are left?
As of September 2023, a relatively high number of 737-200s remain in service compared to other early jet airliners, with fifty examples actively flying for thirty carriers. In October 2025, following Boeing’s crisis caused by accidents in years 2018 and 2019, Airbus A320 family overtook Boeing 737 as the most-delivered jetliner with 12,260 deliveries in total at the time.Boeing is considering designing a new single-aisle aircraft to potentially replace the 737 MAX, a multi-year, multi-billion dollar undertaking. The potential new jet would likely be larger than the 737 MAX, carrying 200 to 250 passengers, competing with the Airbus A321neo.
