The Boeing 737 Family

Hello Community!

This is a new series I will do on specific aircraft or aircraft families. Today I will begin with the iconic Boeing 737. Feedback is welcome; request an aircraft or family in the comments below!
Note: I will only be talking about the NG (Next Generation) aircraft. I will not be talking about military, BBJ’s or the MAX aircraft.

The Boeing 737 NG (Next Generation)

The 737 NG consisted of the these Boeing 737’s:

  • Boeing 737-600
  • Boeing 737-700
  • Boeing 737-800
  • Boeing 737-900

About the 737NG

The Next Generation Boeing 737’s (commonly abbreviated as 737NG) is the name given to the -600/-700/-800/-900 Boeing 737’s and follows the classic 737 family. The 737NG is a short to medium haul range, narrow-body aircraft. The 737NG’s main competition is the Airbus A320 family.

The 737NG Variants

The 737-600

The Boeing 737-600’s launch customer was SAS Scandinavian Airlines and was launched in March, 1995 with the first aircraft delivered in September 1998. The last aircraft was delivered to WestJet in 2006. The aircraft has focused on competing against the Airbus A318 and was to replace the -500 classic variant. A total of 69 aircraft were produced. Winglets were not an option on the -600 but WestJet was meant to introduce them but dropped them in 2006.

The 737-700

The 737-700 was launched in November 1993 when Southwest Airlines ordered 63 of the aircraft and took the the first one in December 1997. It was to compete with the A319 and to replace the -300 variant. Winglets were and option and were implemented on almost every aircraft. 1,127 were produced. By June 2018 1,000 were still in service: half of them with Southwest Airlines, 56 with WestJet and 39 with United Airlines. The remainder are either military aircraft or BBJ’s. The variant came with the 737-700ER (Extended Range) with All Nippon Airlines and featured the -800 landing gear and wings. It also came with up to 9 auxiliary fuel tanks, though the -700ER is no longer in service.

The 737-800

The 737-800 is a stretched 737-700. It was to compete with the A320 and replace the 737-400 variant. It filled the gap made by the decision to discontinue the McDonnell Douglas MD-80 and MD-90 aircraft following Boeing’s merger with McDonnell Douglas. For many U.S airlines, it replaced the ageing Boeing 727 trijets. The 737-800 was launched in 1994 by Hapag-Lloyd Flung (now TUIfly) and entered service in 1998. As of May 2018, 4,817 aircraft are in service with the largest carrier; Ryanair, operating 400 of the aircraft.

The Boeing 737-900 and -900ER are the longest variants to date. The 737-900 was launched by Alaska Airlines in 1997 and entered service in 2001. The aircraft was made to compete against the Airbus A321. The -900ER was launched by Lion Air and entered service in 2006. The 900ER carries the most passengers out of all the 737NG aircraft. It was made to directly compete with the Airbus A321. As of May 2018 52 -900 and 461 -900ER’s are in service.

Just so you know, the -900ER can carry more pax due to updated exit config than the -900.

Alright! Thanks for that information!

Look, I did not like this plane very much, but I learned to fall in love with it.
