Why fly to Sioux City?
United runs the show at SUX, connecting you to two genuinely useful hubs: Chicago O'Hare and Denver International. That's it, but think about what those two cities. ORD at 700 km is your hub to basically anywhere in the eastern hemisphere — transatlantic fares out of Chicago can be seriously competitive, especially in Y or W fare classes if you're chasing upgrade eligibility.
