It filled also the gap left by Boeing's decision to discontinue the MD-80 and [[McDonnell Douglas MD-90|MD-90]] aircraft, following Boeing's merger with [[McDonnell Douglas]]. The 737-800 is the most widely used narrowbody aircraft and competes primarily with the Airbus A320.<ref name=B738>{{cite web|url=https://www.mro-network.com/airframe/boeing-737-800-not-expected-peak-until-2021|title=Inside MRO: Boeing 737-800 Not Expected To Peak Until 2021|last=Derber|first=Alex|work=MRO Network |date=June 14, 2018|publisher=Aviation Week & Space Technology|access-date=August 17, 2018|archive-url=https://web.archive.org/web/20180818052311/https://www.mro-network.com/airframe/boeing-737-800-not-expected-peak-until-2021|archive-date=August 18, 2018|url-status=live}}</ref>
