STL is getting awful close to a WN Fortress Hub -- thankfully not pricewise yet. But if you want to go to a city that is NOT one of the Big 3's Hubs, WN flies a lot of nonstop flights across the country in & out of STL. Probably due to the Central location AND the Point-to-Point system, as it makes Midwest airports natural "hubs"
From what I understand WN is expanding into the old TWA "D" Concourse Gates that have been unused and closed for years at STL
