The journey from Conroe to Phoenix spans roughly 1,200 miles across the American Southwest. Driving via I-10 West is the most direct road route, taking approximately 17 to 19 hours. For faster travel, a direct flight from George Bush Intercontinental Airport (IAH) to Phoenix Sky Harbor International Airport (PHX) takes about 3 hours. You will transition from the humid climate of East Texas to the arid, high-desert environment of Arizona. Both options offer unique perspectives on the changing geography of the Southern United States.
