Having deferred the Northwest Airlines order for 787-8’s that it inherited when the two airlines merged, Delta Air Lines later converted the order to the larger 787-9 variant. The aircraft allowed Delta to finally phase out its massive 767 fleet. This set includes a diagram on how to stretch the Hasegawa kit into a 787-9, or you can also use this set on a straight 787-8 build by deleting cabin windows fore and after of the wing.
