Duty-free allowances: USD 500 in goods. Mexico prohibits importing certain foods and medications without documentation. Declare cash over USD 10,000.
IAH has no direct rail link to downtown Houston. The IAH Express bus runs from Houston Amtrak/Greyhound station via Park & Ride to Terminal C (60–90 min, $1.25 with METRO Q card). This is the only transit option; Houston's rail network does not reach the airport.Taxis from downtown Houston cost $50–70 and take 40–60 minutes. Ride-hails (Uber, Lyft) are typically $35–55. IAH sits 23 miles north of downtown on the North Freeway (I-45); traffic is heavy during morning and evening rush. Remote economy parking lots serve all terminals via shuttle.
Use only authorized airport taxis (purchase vouchers at official booths inside arrivals; do not take street taxis outside). Rates are zone-based: Centro/Zócalo MXN$180–250, Polanco MXN$250–320, Santa Fe MXN$350–450. Uber is not permitted for airport pickup at T1 (walk to street level at T2 to use Uber).Metrobús Line 4 to Buenavista (Metro hub) takes 30–40 min (MXN$12); a solid budget option. Metro Line 5 serves Terminal Aérea (T1). ADO buses depart from T1 to Puebla, Querétaro, and other cities. A second airport (AIFA, NLU) exists northeast of the city; confirm which airport your flight uses.
High-altitude subtropical climate at 2,240m. Temperatures are mild year-round (7–22°C) with little seasonal variation, no extreme heat or cold. The rainy season (May–October) brings daily afternoon thunderstorms, typically between 3–7pm, which frequently cause delays and can be intense. Hail is possible.
Dry season (November–April) offers the most reliable flying conditions. The airport's elevation means aircraft have reduced performance on hot days. Dense morning smog is common in winter inversions and occasionally reduces visibility. Earthquake risk (significant for Mexico City) has no direct flight impact but is worth knowing.
