Getting to LAS

The airport is 5 miles from the Strip; ride-shares and taxis take 10–20 minutes from the Strip ($15–25). There is no rail link.The Las Vegas Monorail does not serve the airport. RTC bus Route 109 connects the airport to the Strip ($2, 20–30 min), but luggage handling is inconvenient. Hotel shuttles from major resorts are the most hassle-free option and often free for guests.

Getting from IAH

Ride-hails pick up at the designated Rideshare zones outside baggage claim on the lower level.IAH has five terminals (A–E) connected by an underground tunnel with trams. Terminal D handles international arrivals. Rental car agencies are in a consolidated facility adjacent to Terminal C; a free IAH Connector bus runs between terminals and the rental car center. The Galleria / Uptown area costs $35–50 by ride-hail.

Houston Climate

Humid subtropical climate. Hot, humid, and wet for much of the year. Summers are brutal (33–38°C) with high humidity and near-daily afternoon thunderstorms. Severe storms with hail and high winds regularly cause ground stops from April through September. Houston's flooding risk is significant. Heavy rain events, including tropical system remnants, have flooded airport roads, cutting off surface access even when the airport itself remains operational.

Winters are mild (5–18°C) with occasional ice storms. These are rare but highly disruptive when they occur. Hurricane season (June–November) requires monitoring for Gulf storms. October through March has the best flying weather.
