December is a peak holiday travel month for the Houston (All Airports) (HOUA) to Chicago (All Airports) (CHIA) corridor. Nonstop flights—typically 2 hours 40 minutes to 3 hours—run frequently on United (IAH–ORD), American (IAH–ORD/HOU–ORD schedules), and Southwest (HOU–MDW), with added connecting options via Dallas, Charlotte, and Denver. For the best December deals on round-trip and one-way fares, book 3–8 weeks ahead, fly midweek (Tuesday–Thursday), and use price alerts for flash sales. Travelers should avoid the core holiday window (December 20–27) for cheapest rates but consider last-minute mid-December bargains. Nearby major destinations reachable from Houston before departure include Galveston, Austin, San Antonio, Corpus Christi and Dallas/Fort Worth; on arrival, Chicago’s attractions and suburbs such as Evanston and Naperville are easy to access. CTA and Metra rail, rideshares, and airport shuttles provide reliable transfers at Chicago airports. CTA Blue Line serves O'Hare (ORD) and the Orange Line serves Midway (MDW), but winter delays and de-icing on arrival can add time—plan accordingly. Book cheap flights from Houston to Chicago this December using flexible date searches and consider refundable or protected fares during holiday weather windows.
Arriving at Chicago (All Airports) (CHIA) in December means facing winter temperatures, possible snow, and high tourist demand for holiday markets and events. Prioritize morning or early-afternoon arrivals to reduce risk of weather-related cancellations and to take advantage of public transit (Blue Line from ORD, Orange Line from MDW). For access to suburban destinations like Evanston and Naperville, use Metra commuter rail lines from downtown or regional rideshare/park-and-ride options. To avoid holiday surcharges and long waits, pre-book airport transfers and confirm hotel arrangements. Book your December flights to Chicago early and monitor weather advisories to ensure a smooth arrival.
