I live in Mukilteo and have been to the city meetings. Generally, I think the locals are just worried that once the door is open to 4 allegant and 14 horizon/Alaska flight it'll be much more difficult to stop expantion later on.

A lot of people were also worried about turbo prop noise and their property values, which didn't make any sense. That dash is quieter than most of the piston AC flying out of PAE. The MD on the other hand... Even as someone who would enjoy some service at PAE, I'm still a little concerned as a home owner. Even if it's due to irrational fears of my neighbors.
