Pickup tips for economy renters at CMI

Three things to know before you commit to a economy at University of Illinois Willard Airport. First, ask the counter agent which specific model is on the lot — published class definitions vary, and at busier airports like CMI the agent will often offer a free upgrade to clear inventory. Second, inspect the vehicle thoroughly before leaving the lot. Photograph all four corners, the wheels, the windshield, and the interior; rental damage disputes are settled by who has the better evidence. Consumer protection groups recommend keeping these photos for at least 90 days after the rental ends.

Third, if you're picking up after midnight, confirm in advance that the counter will hold your reservation — some CMI rental locations release no-shows as early as 30 minutes after your scheduled pickup, especially for higher-class vehicles like economy that get rebooked quickly. The cheapest brand here right now (Enterprise at $31/day) may not be the best for late-night arrivals; National and Hertz typically have the most reliable after-hours staffing at major airports.
