I thought Boeing CEO already said they're going to make a all new 737 replacement?

No.Boeing said that they would take until the end of 2011 to decide what to do about the 737.

Yeah, rechecking quotes the decision seems it isn't set in stone but thats the way they're goinghttp://www.flightglobal.com/blogs/flightblogger/2011/02/boeing-ceo-jim-mcnerney-were-g.html

Speaking at the Cowen and Company Aerospace and Defense Conference in New York City, McNerney says: "We're gonna do a new airplane. We're not done evaluating this whole situation yet, but our current bias is to not re-engine, is to move to an all-new airplane at the end of the decade, or the beginning of the next decade."

In fact the situation is so fluid that may change multiple times. For example today , when you read about the latest negotiation between Boeing and American Airlines it is said that Boeing is leaning towards putting new engines just to keep AA happy and win their big order. Putting new engine will not preclude developing new aircraft but will further delay it. Your source dates back to February and since then their thinking evolved.

i think that it would be a great idea to start over with the 737, or at least re design the aircraft and use the materials that are being used with the 787 and 747-8.they are in fact as you can see in the video re-designing the wings, and the market is demanding a more efficient aircraft like the Embrear as an example.i think it would be a good time to start working on a brand new 737 and make the most popular commercial jet airliner stay the most popular.I know we all love the design as it is now but why not go crazy, can you imagine a new cockpit, new more efficient engines, new body, they have the basics of doing all that.But it is always the money. i guess that is the issue don't you think? Will see how Boeing will handle this.CheersJeffrey.

Jeffrey,Indeed, it is nice to keep designing new aircraft but as it was explained recently in a very probing article the sheer numbers work against you.By re-engining you get about 5% improvement in operating costs.By redesigning the total airframe you get another 5% for a total of 10% (my numbers are rough).Yet airlines are expecting about 15% total improvement when they buy a new generation aircraft.It is very, very hard to come up with the remaining 5%.The new 737 would not be available for service until 2020 - way too long to wait for many (like American Airlines)and in the meantime you are losing ground to competition. And development of an all new aircraftcosts fortune and is not without risks.It is not easy to juggle all the prons and cons.

Whoops. I don't think I want to see that. Sorry, couldn't help myself.

Haha... SHIP Now where's the edit button??

I agree.. Something extraordinary has to happen imo with the 737. While the A320NEO is the exact same airplane but re-engined (as far as I know) as the current A320, airlines will receive the A320NEO in 2014-2016 most likely even later too. Then Airbus could prepare for a new type for 2020. So I think Airbus is covered pretty good compared to Boeing. But that's just my opinion

Yeah your right about that its a struggle for those guys everyday. but to see some improvements on the aircraft is a good thing. now they have done it with the wing tip for the navy,i hope they will pass it on to the commercial planes i just love the wing tips like that :( thanks for your reply.Cheers Jeffrey
