The Super Twin Battle: A350-1000 versus 777-9X

With the forthcoming launch of the 777-9 at the Dubai Air Show next
month, the battle between the A350-1000 and 777-9 will be officially on,
with two very different aircraft competing for the same market.  While
there is discussion of another stretch to the A350 program to provide
comparable capacity to the larger 777-9, we can compare today’s aircraft
and examine their relative economics based on manufacturer projections
and Piano models based on preliminary specifications.

The A350-1000

The A350-1000 is the largest of 3 models in the A350 family, with 350
seats in a typical three class configuration, with an 8,400 nautical
mile range.  The A350 features carbon fiber composite structure and
wings, and at 53% composites will have slightly more of the aircraft
made of this material than the Boeing 787-9, which is 50% composites. 
It features new technology Trent XWB engines from Rolls Royce with
state-of-the art fuel efficiency, advanced aerodynamics, and state of
the art systems.

The 777-9X

The 777-9 is a stretched version of the current 777-300ER with a new
engine and new wing, along with other enhancements, to create an updated
version of the 777, which delivered its 1,000th example earlier this
year.  The 777-9X will feature an aluminum alloy fuselage with a carbon
fiber composite wing, and new technology GE9X engines that are derived
from the GE90 and GEnx families.  The wingspan for the 777-9 will be
longer than any Boeing aircraft, and will include folding wingtips to
enable the aircraft to utilize current gate positions at airports, as
otherwise the new model would require gates typically used for A380
operations (which are currently quite limited at congested airports.)

Comparing the Aircraft

The following table compares the two aircraft on several key statistics, based on preliminary data prior to the 777-9X launch:

The A350 cabin width is larger than the 787 and smaller than the
777X.  The result is that a typical configuration in economy would be 9
abreast at 17 inch seat width for the 787, 9 abreast at 18 inch seat
width for the A350, and 10 abreast using 17 inch seat width for the
777.  While the 777 is currently offered in 9 and 10 abreast seating,
recent orders have trended to 10 abreast seating as airline seek to
maximize seat-mile costs.


Both manufacturers are claiming class leading economics for their
airplanes, but in reality, they are very, very close.  The 777-9 holds a
16% advantage in capacity, which directly impacts seat-mile costs, but
the A350-1000 will have lower trip costs than its larger competitor. 
Our estimates for a 6,000NM trip, based on preliminary specifications
from airframe manufacturers, our own economic modeling, and data gleaned
from airlines, are as follows:

very comparable seat-mile costs, the A350-1000 and 777-9X will be
competitive, and it will come down to how many seats an airline believes
it can fill.  For those that can fill 400 seats, the 777-9 looks like a
good alternative, for those that prefer a lower risk, the 350 seat
A350-1000 is the right airplane.
The key question, as the OEMs continue to one up each other, is
whether an A350-1100 stretch will be built. The A350-1100 would be an
all new technology aircraft competing with a highly modified but
derivative model, and should have both lower aircraft mile costs and
lower seat mile costs than the 777-9.  A stretched A350 would also help
to bridge the large gap in size between A350-1000 and A380-800.

We believe the A350-1100 will become a competitive necessity for
Airbus.  With the A350-1000 due for EIS in 2017, and the 777-9X due in
late 2019 or 2020, there is still time for Airbus to bring out an
additional model in time to check the size advantage for Boeing.  As
airlines are looking to larger twins to replace 747-400 with aircraft of
similar capacity, the time is right for these “super-twins” in the
