        "answer": "A nonstop flight from Chicago to Houston typically takes about 2 hours 45 minutes to 3 hours.

        "question": "What are the ground transportation options in Houston?",
        "answer": "Houston's George Bush Intercontinental Airport (IAH) is about twenty-three miles from downtown. The most affordable public transit option is the METRO Bus Route 102, which connects the airport to the Downtown Transit Center in roughly one hour, though service frequency is limited. Houston has no direct rail link to the airport, making it less transit-friendly than many major cities. Taxis are readily available outside arrivals but are expensive for the distance. Ride-share services like Uber and Lyft are the most commonly used option, offering a balance of convenience and moderate cost with trips typically taking thirty to forty-five minutes depending on traffic. Shared shuttle vans provide a cheaper alternative to taxis. Car rentals are popular given Houston's car-dependent layout and are a practical choice for visitors planning to move around the city. Most travelers opt for ride-share due to the limited public transit options and the sprawling nature of the city."
