I've been wondering for a while now, Spokane Airport has the word "International "on it yet the few times I've been there, I've yet to see a single none american airline to service there or an American airline servicing to a none American city.

Canada, Mexico ( Puerto Vallarta, Cancun), and Costa Rica.

Canada trips

Occasionally a charter flight may come in from another country which makes it international

It's because when it had its old name Manley became an airport for connecting flights going into Canada and now it has flights all over the US and some in Canada
