PSC Will Fly You Non-Stop to Chicago
You wanna see the real Windy City? Take a hop to Chitown. Starting in June 2020, you'll be able to board your flight at Tri-Cities Airport and reach Chicago without boarding a second plane. I don't know how much you travel, but avoiding potentially long layovers reduces a lot of stress.
The flights will be through United, and will leave Pasco at 11:30 PM, setting arrival in Chicago (ORD) at 5:07 AM. This will be the airport's first "red-eye" flight, meaning late night flight.
The Tri-Cities Airport already offers several non-stop flights to major United States cities, including Seattle, Los Angeles, San Francisco, Phoenix-Mesa, Las Vegas, and Denver. If they were to add New York City and Houston, they'd have all 5 of the largest US cities.
