There is the never-ending "war of words" between Airbus and Boeing of which aircraft is the more fuel efficient one, and, since the launch of the A320neo, if the A320neo would be more fuel efficient and if yes, by what margin. Further complicating, Boeing meanwhile claims, that it's yet-to-be-named reengined B737 would have the same advantage in terms of fuel efficiency as the current generations of these two narrowbodies have. And as even Boeing does not seem to know how the exact configuration of the reengined B737 looks like, this claim seems (at least) a little bit premature.
As I tried to lay out in an earlier posting, much depends on what you want to compare: fuel burn per trip of fuel burn per passenger.

Shifting center of gravity
Looking at the regional distribution of A320neo sales we get aware of the change in aviation.
South and Southeast Asia is where the coming aviation markets are - almost 550 A320neo are ordered for these markets when we count the 78 for Jetstar also for that region. And there should be more to come: China did not order the A320neo so far, but I guess we can bet on an order sooner or later.

Embraer 2000nm 5 abreast
It is no secret that Embraer looks into building a CSeries rival with an own 5 abreast aircraft. But as Bombardier's CSeries will offer a maximum range of 2950nm and the wing is designed for that range, Embraer reportedly is looking for a range closer to 2000nm, but thinks about a little larger aircraft. Scott Hamilton wondered in a recent blog entry how Embraer could achieve to build a lighter aircraft, as Ronald Epstein, the BoA analyst suggested. Here is a quick explanation:

B737RE Early Fuel Burn Analysis
Scott Hamilton picked up a few interesting details from the Boeing Quarterly Earnings Call regarding the B737RE. The most important question regarding this program remains the fan diameter. It looks like it will settle around 66 inches, so that Boeing can go forward without touching the nose gear.
But what does that mean for fuel efficiency?

The 130 seater market
The launch of the CSeries in July 2008 initiated many discussions about the market those two aircraft are placed: the 110-130 seater market.
