The United States Federal Aviation Administration (FAA) has a system for categorizing public-use airports (along with heliports and other aviation bases) that is primarily based on the level of commercial passenger traffic through each facility.
 It is used to determine if an airport is eligible for funding through the federal government's Airport Improvement Program (AIP).
 Fewer than 20% of airports in the U.S. qualify for the program, though most that don't qualify are private-use-only airports.

 At the University of Illinois at Urbana-Champaign, which lies within the District, all 42,883 students pay a $59 transportation fee every semester in 2014-2015 in exchange for unlimited use of the bus services.
 The District currently levies about 28 cents of property taxes per $100 of assessed valuation.
 The seven members of the Board of Trustees are appointed by the Champaign County Board.
 Although Willard Airport lies outside the boundaries of the district, MTD offers District residents bus service to and from the airport on routes funded by the University.
 Buses are produced by the Canadian company New Flyer, Eldorado, and Gillig.
 MTD introduced hybrid buses to its fleet in Fall 2009, while sprinter vans are produced by Mercedes-Benz.
