Uhhh, no, they don't.
Both companies announce at major shows.
Boeing is losing single aisle share to Airbus due to NEO, and will not catch up until they announce 737 replacements.
Announcing at an air show is great publicity for the buyer, and it's usually the Asian carriers who like this flash.
But if you look at the total order book for 737s and A320 NEOs, you'll see why Boeing isn't in a panic to jump on the NEO bandwagon.
The 737 has enjoyed a performance margin over the A320. NEO closes this gap, but doesn't surpass the 737.
Yes Airbus may be wining the larger share of new orders, but to keep up with market demand and an unbelievable backlog of over 2100 737s waiting to be built, Boeing is building 35 737s month in 2011 and will produce 42 737 airplanes per month by mid-2014.
Putting that number in perspective, Boeing built 14 a month in 2003, 17 in 2004, 21 in 2005, and a record 28 a month in 2007.
And the backlog in 2001 was less than a thousand airplanes in the backlog. With over 2100 now, Boeing must turn them out faster just to have spots to put new orders.
Boeing 737 is alive and well.
