- Airport congestion at IAH and LAS can add 30–60 minutes to the overall journey during busy times.
Road Conditions
- Construction zones along I‑10, especially in New Mexico and Arizona, may force detours that add 1–2 hours.
- Mountain passes near Flagstaff can be affected by snow in winter, requiring chains or alternate routes.
Practical Tips for Travelers
