If you mean Y1, then between AA
alone, Boeing would have an up to 900 aircraft order book for 15 years, which would make it worthwhile. All they need is to offer an aircraft that is better than the 737NG, MD80 and 752 in a real way that makes it worth buying rather than keeping the other jets for 20 more years.
Other carriers would include those in Japan, AS
, Ryanair and other LCCs that fly current 737s and 757s and hasn't shifted to an A320 replacement scheme, potentially certain carriers who currently fly the A320 series in bulk (but only if the new plane was so much better and Airbus wasn't competing with a new A320 for some reason). B6
are two that could be swayed if the price and product were right.
has already stated they want B to offer a replacement sooner rather than later, and AA
would be on board, as CO
could use more 752 type planes in the future, and AA
needs to start replacing 752s and MD80s at some point, and the 738 can't do it all.
Of all the things to worry about... the Wookie has no pants.
