Boeing has confirmed it has ended production on the commercial 737NG, following delivery of two 737-800 aircraft to China Eastern Airlines, the company said.
Southwest took delivery of the first 37NG, a 737-700, in 1997, and in Boeing´s 22 years of production, Southwest took delivery of 689 of the jets, according to Cirium.
Boeing said it delivered the final 737NG to come off its production line to KLM Royal Dutch Airlines in December 2019, but the final delivery went to China Eastern in January.
Since production began, Boeing said it has delivered approximately 6,900 737NGs to commercial carriers, its data shows.
Boeing would go on to deliver 69 737-600s, 1,150 737-700s, 4,989 737-800s, 52 737-900s, 505 737-900ERs and 149 737NG-based Boeing Business Jets.
The 737NG was replaced by the 737 Max which has new, more efficient engines.
Boeing has also delivered several hundred military variants of the 737NG, one of which, the P-8 Poseidon maritime surveillance aircraft, remains in production.
