Over the next 4 years they plan on removing 40 757's from service. That number is flexible depending on the economy and demand. The 900 is the replacement. Same seating however total operating costs about 30 percent below the 757. The 900ER can fly 95 percent of the current 757 routes without any real capacity restrictions. The other 5 percent will eventually have to be covered with another airframe however some 757's are projected to remain in service until 2024 so there is a lot of time for deciding on that airframe. At the moment there is no airframe in production that can cover those routes. Think 5700 foot runway at SNA going with a full load and IFR reserves to Atlanta. Nothing can touch the 757 for those types of operations.
