True, but for the first 717 awards, I'm going to assume those WB FO's will be competing with displaced DC-9 A's. Same concept on the 737-900: they are supposed to be offset by 767-300/757/320 retirements.

In theory, the retirements could lag behind the deliveries, but I'm just as much of a MD-88 A, in theory, as little Johnny is a millionaire in theory.

In reality...
