The reduction of the 50-seaters is tied to the addition of 76-seaters which are tied to the delivery of the 717. End state, after all 717 deliveries, assuming Delta utilizes all of the allowed 76-seaters, there will be a cap of 125 50-seat aircraft of up to 65,000 lbs. As the 50-seaters are progressively reduced, zero future growth of that permitted aircraft type is allowed. Based on delivery schedules, the cap of 125 50-seaters would not come into play until sometime in 2015, although Delta could always reduce them ahead of schedule without restriction under the PWA.
