Thinking about MDD's rather limited product range, vs Boeing's pretty much
complete range of >100pax aircraft (and Airbus's not-quite-as-complete but
still better than MDD's)...

How much commonality is there between Boeing models that wouldn't be there if
you ran a mixed fleet -- eg is there a significant advantage to flying an
all-Boeing fleet, say 737s & 757s vs flying a mixed fleet (eg A319s instead of
737s)?  Boeing makes quite a song & dance about being the only manufacturer
to offer the "complete" range (although that really does rely on the 737-800
filling the A320's slot, which isn't in service yet).  But there's no engine
commonality (except between the 767 & 747), and the airframes are quite
different.  Is there enough in common (avionics etc) to swing a decision
from running a mixed fleet?
