"Hi Pat."
"Did you get the proposed trip I sent over? Better book soon, because this big-city tour is going fast!"
"Well, if this is the route map you want me to choose from, I don't think this airline is going to be in business very long. Seattle must be one of the worst cities in America to have a hub in, especially with all these cross-country flights."
"Sometimes missing a flight provides a new destination."
"Very Zen, Pat, but I'll take the insurance on this one. Well, it looks like all roads lead to Seattle, so let's book to Seattle."
"Oh, you're not going to Seattle!"
"Then why did you send me the...oh, another puzzle?"
"On your mark, get set, go!"
Well, Pat's doing it to me again. Can you help me figure out where I'm headed this time? I've included a copy of the route map Pat sent me, as well as a couple of insets. Note that the Hawaii inset includes a route not on the main map, but that is the only exception.

HINTS
I probably should have added the "pattern" tag to this puzzle. You don't need to determine every location on the map to solve the puzzle...if you can spot the pattern!
There are three termini in Missouri; none has a population greater than 6,000, but each is connected to a much larger city.
Recommend starting with the western inset map...there are a couple of links there with two larger cities that might give you a corner to pick at. Also, I've added the knowledge tag, since picking at this corner might require a bit of research.
