Getting to IAH

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.

Getting from BKK

Airport Rail Link runs to Phaya Thai in 30 minutes (฿45). Runs 6am to midnight. Connect to BTS Skytrain at Phaya Thai for onward travel to Sukhumvit, Silom, or Siam.Taxis from the arrivals level are metered; add the ฿50 airport surcharge and expressway tolls to the meter reading. Total to central Bangkok typically ฿300–450. Grab is reliable and avoids negotiation. Limousine services (฿800–1,500) are available from the arrival hall. Buses are cheap but slow given Bangkok's traffic.

Bangkok Climate

Tropical monsoon climate. Hot season (March–May) reaches 38–40°C with high humidity. Wet season (May–October) brings daily heavy rains and occasional flooding. Thunderstorms cause flight delays regularly. Suvarnabhumi sits in a flood-prone area east of Bangkok. The 2011 floods came close to the airport perimeter.

Cool season (November–February) is the most comfortable for travel (25–32°C) with lower humidity and good flying weather. Haze from agricultural burning occasionally reduces visibility in March–April.

Check current weather forecasts before travel.
