        "question": "What are the ground transportation options in Chicago?",
        "answer": "Chicago has two main airports serving international and domestic flights. From O'Hare, the Blue Line CTA train reaches downtown in about forty-five minutes and is the most popular option due to its low cost and reliability. Taxis and ride-share services like Uber and Lyft are widely available but can take longer and cost significantly more depending on traffic. From Midway, the Orange Line CTA train reaches the Loop in about thirty minutes and is equally practical. Shared shuttle vans offer a middle ground between transit and private rides. Car rentals are available at both airports and suit travelers heading beyond the city, but downtown parking is expensive and traffic can be heavy. The Blue Line from O'Hare is the most commonly used option overall, favored by both tourists and business travelers for its flat fare and direct downtown access."

        "question": "How far in advance should I book tickets from Houston to Chicago?",
        "answer": "For Houston (IAH) to Chicago, the optimal booking window is about 3–6 weeks before departure, where average fares sit around $196, with the sweet spot right at 30 days out (roughly $191). Booking too early — say, 5–6 months ahead — can actually cost significantly more ($300+), and last-minute fares spike to over $500, so for summer travel or holiday periods when demand is high, aim for the earlier end of that window (around 6 weeks out) to lock in availability before prices climb.",
