Book Your Adventure from ORD to LAS: Cheap Flights from Chicago to Las Vegas

Consider flying mid-week, specifically on Tuesdays or Wednesdays, to avoid the heavy weekend crowds and significantly lower your fare costs, as Friday arrivals and Sunday departures are typically the most expensive. Since the flight duration is roughly four hours, bring an extra layer or a light jacket; although Las Vegas is scorching hot, the cabin pressure and Chicago’s unpredictable weather often make for a chilly start to the journey. Download your airline's mobile app before arriving at ORD to receive real-time gate updates and digital boarding passes, which is essential given the massive size and potential foot traffic at O'Hare. If you plan on using rideshare services upon arrival at LAS, follow the specific signs for 'Ride Share' located in the parking garage levels, as they are separate from the standard taxi lines.

Fares for the ORD to LAS route typically peak during the winter months and early spring when Chicagoans seek refuge from the freezing temperatures in the desert sun. Additionally, major conventions like CES in January or high-profile sporting events can cause prices to skyrocket overnight. Conversely, the heat of the summer months, particularly July and August, often sees a dip in ticket prices as the extreme desert temperatures deter some leisure travelers, making it the ideal time for bargain hunters.
