The best time to fly from Chicago O'Hare International Airport (ORD) to Jacksonville International Airport (JAX) in December is typically mid-week (Tuesday–Thursday) and earlier in the month (first two weeks) to avoid holiday surges and highest fares. Early-morning nonstop flights can reduce the likelihood of weather delays accumulating through the day at ORD, while late-evening departures sometimes have lower fares but can be riskier if severe weather is forecast.

Nonstop flights from Chicago O'Hare International Airport (ORD) to Jacksonville International Airport (JAX) generally offer the fastest and most reliable option in December, minimizing the risk of missed connections during winter weather.

For holiday travel, weigh the value of time versus savings: if you need guaranteed arrival windows, choose nonstop; if you're price-sensitive and have flexible timing, consider one-stop routes.
