Brad's Deals Editor Jacob,
Book round-trip flights to Cancun from Chicago with prices from $214 at Kayak. We found the lowest price on a one-stop Frontier flight in May. Nonstop flights start at $253. Frontier is a budget airline, so please note that baggage costs extra. You can compare prices for cheap flights to Cancun, then book online. Taxes, fees, and exclusions apply.
