Apparently the "300 flights by 2017" was also talking about flights going from SEA to LAX and then LAX to SEA as those are equally damaging to Alaska Air Group as increased SEA departures alone. They were playing up the numbers on their side to let the employees know the threat is real and to increase levels of customer service as a way to fight back.

That said, Delta will still have equal to or more mainline flying out of SEA as Alaska by the end of 2016 if the current plan is executed. Since we have not heard of any new categories being added to SEA for this summer we must assume 737's will flow in and out along with some 757 (ie Juneau) to cover the increase. More flying running up to 2017, still leaves question marks. It would be interesting to find out if a new category is in the works as that would radically change the landscape for pilots based in the PNW (ie SEA based senior FO's might elect to take a narrowbody captain position opening more total slots for those looking to be based in SEA).
