Wide-body mix in 15 years of Boeing CMOs

A couple of days ago I wrote about the publishing by Boeing of its Current Market Outlook for 2013-2032. In that post I made a very brief review of it, and mentioned that I was puzzled by the change in the predicted mix of twin-aisle sales, between small and medium wide-bodies. To recall the numbers:

• small wide-bodies: from 2,720 a/c in CMO2012 to 4,320 a/c in CMO2013, whereas,
• medium wide-bodies: from 4,490 a/c in CMO2012 to 2,810 a/c in CMO2013.

Since I keep a collection of CMOs from years back, I decided to compare the figures of this wide-bodies mix along the last 15 years…

Twin-aisle mix distribution (Boeing CMO 1998-2013).

Seeing at the graphic (made using Boeing figures):

• During the first 5 years (1998-2003) the trends are quite constant.,
• From 2003 to 2007, the mix is reverted, possibly to favour the launch of the 787.
• In 2008 the CMO did not provide the split.
• From 2009 to 2013, you can see that both trends in the forecasts are erratic… why? Only Boeing knows.
