        "question": "Are there visa requirements to travel from London to Chicago?",
        "answer": "Visa requirements depend on your nationality. UK citizens traveling to Chicago can visit the US without a visa under the Visa Waiver Program but must obtain ESTA authorization before departure, which costs $21 and is valid for two years. US citizens returning home need no visa. Nationals of other countries should check if their country participates in the Visa Waiver Program; if not, a B-1 or B-2 visa is required. Coming the other way, US citizens visiting the UK for short stays must now obtain a UK Electronic Travel Authorization (ETA), required from January 8, 2025, costing 10 pounds."

        "question": "What are the ground transportation options in Chicago?",
        "answer": "Chicago has two major airports serving international arrivals. From O'Hare (ORD), the CTA Blue Line train reaches downtown in about forty-five minutes and is the most popular option due to its low cost and reliability. From Midway (MDW), the CTA Orange Line connects to the Loop in roughly thirty minutes. Taxis and ride-share services like Uber and Lyft are widely available from both airports but can be significantly more expensive and slower during peak traffic. Shared shuttle vans offer a middle ground in cost and convenience. Car rentals are available at both airports and suit travelers heading beyond the city, though downtown parking is costly. The CTA train is by far the most used option for budget-conscious and time-sensitive travelers arriving at O'Hare, offering a direct and predictable journey regardless of road conditions."
