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.
PHX Sky Train (free, 24h) connects T3 and T4 to the 44th Street/Washington light rail station in 5 minutes. Valley Metro Rail reaches downtown Phoenix in 20 minutes ($2). Uber and Lyft pick up at Ground Transportation on the lower level; follow signs. Taxis are metered; downtown Phoenix costs $20–30.Rental car agencies are consolidated in the Rental Car Center; the Sky Train connects there from both terminals without going to the street. For Scottsdale, Tempe, or Chandler, ride-hails are practical ($25–50). Express buses serve some suburban destinations.
Hot desert climate. Summers (June–September) are extreme. Daytime temperatures regularly exceed 43°C, occasionally reaching 48°C. Heat alone rarely cancels flights, but density altitude affects small aircraft performance. Monsoon season (July–mid-September) brings dramatic dust storms (haboob) that close the airport when they hit, plus intense flash-flooding thunderstorms that ground departures for 30–90 minutes.
Winters are exceptionally mild (10–22°C) with virtually no precipitation and near-constant sunshine. PHX has one of the lowest weather cancellation rates of any major US airport from November through April. Spring and fall are pleasant; late May and early June are hot and dry before monsoon arrives.
