Direct PHX to ORD Flights: Navigate the Route from the Valley to the Windy City

Prepare for a significant temperature swing, especially during the winter months, by dressing in layers before boarding so you are comfortable upon arrival in Illinois where the wind chill can be biting. Consider booking a morning flight to avoid the potential for afternoon thunderstorms in the Midwest, which can occasionally lead to ground stops or delays at O'Hare during the peak summer season. Additionally, we recommend downloading the mobile apps for your specific airline and the O'Hare airport map, as ORD is one of the largest and most complex airport layouts in the world, often requiring significant walking time between connecting gates. If you have extra time in Phoenix, take advantage of the PHX Sky Train, which offers a free and efficient way to navigate between terminals and the Valley Metro Rail system before your departure.

Flight prices for the PHX to ORD route fluctuate based on the drastic climate differences between the two cities. Typically, the cheapest months to fly are January and February when Chicago's freezing temperatures deter casual tourists, while the most expensive times occur during the summer months of June and July as Phoenix residents flee the desert heat for the mild Chicago lakefront. Mid-week departures, specifically on Tuesdays and Wednesdays, generally offer significantly lower fares compared to peak Sunday travel times.
