        "question": "What is the typical flight duration from Chicago to Houston?",
        "answer": "A nonstop flight from Chicago O'Hare (ORD) to Houston (IAH) typically takes about 2 hours 55 minutes to 3 hours 10 minutes. The return flight from Houston to Chicago usually runs slightly shorter at around 2 hours 45 minutes due to favorable winds. Connecting flights with a layover add at least 1 to 2 hours to total travel time."

        "question": "Are there any direct flights from Chicago to Houston?",

Frontier also flies the route nonstop on select days (Mon/Thu/Fri/Sun), and PSA/OH has a Saturday-only flight, so in total you have nonstop options virtually around the clock every day of the week.",

        "question": "What are the ground transportation options in Houston?",
        "answer": "Houston's George Bush Intercontinental Airport (IAH) is about twenty-three miles north of downtown. The most affordable public transit option is the Metropolitan Transit Authority bus route 102, which connects to the Northline Transit Center where passengers can board the METRORail Red Line downtown, though the total journey can take over ninety minutes. Taxis are readily available outside baggage claim and take around thirty to forty minutes depending on traffic. Ride-share services like Uber and Lyft are extremely popular and widely used, offering a reliable and often cheaper alternative to taxis with similar travel times. Car rentals are available at the on-airport facility and are a practical choice given Houston's car-centric layout. There is no direct rail link to downtown. Ride-share services are the most commonly used option due to Houston's limited public transit infrastructure and the convenience they offer compared to taxis and buses."
