Houston to Shanghai (Pudong) (IAH–PVG) — Airlines, Schedules & Connections

US passport holders can enter China visa-free for stays up to 30 days under a temporary policy running through December 31, 2026. This covers tourism, business visits, and transit. No advance application is needed. Passport must be valid for at least 6 months beyond the date of entry.

For stays beyond 30 days, a standard visa from a Chinese embassy or consulate is required before departure. Separate 144-hour and 72-hour visa-free transit programs exist at select airports for travelers continuing to a third country.

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.

Maglev to Longyang Road (8 min, ¥50) is a fast exit; transfer to Metro Line 2 onward. Metro Line 2 runs directly from PVG T1/T2 to People's Square and Hongqiao Airport (1.5–2 hrs, ¥7). Taxis have a meter; expect ¥130–200 to Puxi (west side) depending on destination and traffic tunnels used.Airport buses serve multiple city zones (¥22–36, 60–90 min). DiDi ride-hail is available and typically cheaper than street taxis for longer distances.

Humid subtropical climate with four distinct seasons. Summers (June–August) are hot and oppressively humid (28–37°C) with typhoon risk. Storms can cause flight cancellations with little warning. Winters (December–February) are cold and damp (1–8°C) with occasional frost. Dense fog disrupts departures regularly in January–February.

Spring is rainy and mild. Autumn (October–November) is the most settled period. Clear skies and 12–22°C make it the best window for travel. Pack layers for shoulder seasons. An umbrella is useful year-round.
