In total there will be 88 of the 717-200s heading to Delta, as Southwest will lease the planes to them beginning sometime next year. The deliveries will trickle in through 2015, so it’ll be quite some time before all the 717s will be flying in their own colors and livery. Delta expects to save like hundreds of millions of bucks in both fuel and maintenance costs thanks to the new planes, so they’re clearly spending some money to make money.
Delta hasn’t revealed any of their plans for possible refurbishments or renovations before adding these planes to their fleet, but we’re pretty darn sure they’ll be WiFi enabled. After all, the planes probably already have the necessary technology bits and pieces from their time at AirTran.
