Cheap Flights from Jacksonville to Chicago
JAX to ORD — Illinois, USA
Why fly JAX to Chicago?
Chicago is a two-airport city (ORD and MDW), and JAX travelers should always check both. American and United operate nonstops to ORD; Southwest is the cheapest option to Midway but requires a connection. Frontier occasionally adds a seasonal nonstop.
Winter is your friend — nobody wants to fly INTO Chicago in January or February, so fares crater. If you can handle the cold, you will find $99-$130 one-ways easily. Summer festival season (Lollapalooza, food fests) is the opposite: fares spike from May through August.
