RJs take essentially the same runway space as traditional jets and only carry 1/4 to 1/3 as many passangers. More airline flights trying to use the same runways, so something has to give. It would appear that the majority of Boeing's airliner production is the 737 (118 to 215 seats*) currently: Boeing Reports Third-Quarter 2007 Deliveries CHICAGO, Oct. 04, 2007 -- The Boeing Company [NYSE: BA] today announced deliveries across its commercial and defense operations for the third quarter of 2007. Major program deliveries during the third quarter were as follows: Major Programs 3rd Quarter 2007 Year-to-Date 2007 Commercial Airplanes Programs 737 81 250 747 5 12 767 3 9 777 20 58 Total 109 329 Integrated Defense Systems Programs Apache (New Builds) 9 17 Chinook (New Builds) 1 7 C-17 4 12 C-32/C-40 0 2 F/A-18E/F and EA-18G 11 33 Satellites (Government & Commercial) 1 4 T-45TS 2 7 F-15 3 6 Delta II - Commercial 1 2 ### * http://en.wikipedia.org/wiki/Boeing_737 Yes, the 737 has been the most popular passenger jet for some time now. But, the number of aircraft delivered by Boeing is not very signicicant... Check the number of aircraft delivered or in use by US airlines and you will find a huge increase in the use of Regional Jets. Remember, Boeing does not manufacture a RJ (neither does Airbus). The big RJ producers are Bombardier (Canadair RJ) and Embracer. Also, you can't look at the aircraft 'owned' by the major airlines because most of the RJs are flown by the "Commuter" airlines (ASA, Comair, American Eagle, etc.) Go to the major airport hubs where the long queues form for takeoff and look at aircraft types... about half will be RJs these days. (Because they fly shorter routes and turn around faster, they make more take-offs and landings than larger, 'standard' jets, compounding the problem.)
