It’s clear why the Regional Transit Authority is suing United Airlines. But why is it suing the City of Sycamore?

The transit agencies which comprise the RTA – Pace, Metra and the Chicago Transit Authority – are continually fighting over funding. RTA needs more revenue.

So they’re going after Chicago-based United Airlines, which operates a subsidiary company, United Aviation Fuels Corp., with an office in Sycamore. The company orders jet fuel for United, and pays sales tax on the purchases in DeKalb County, where the tax is 1.5 percent lower than in Chicago.
