        "question": "Which cities in Illinois can I fly to directly or with one stop from London?",
        "answer": "From London, you can fly directly to Chicago O'Hare, the primary gateway to Illinois. One-stop options are available to other Illinois cities like Springfield or Peoria, typically connecting through Chicago or other major U.S. hubs. For most travelers, Chicago is the main entry point, while regional airports are chosen for proximity to central or downstate destinations."
      },
      "q1": {
        "question": "How long is the flight from London to Illinois?",
        "answer": "Non-stop flights from London to Chicago O'Hare typically take around 8 to 9 hours westbound, with the return eastbound leg often about an hour shorter due to prevailing winds. One-stop itineraries to other Illinois airports like Midway or downstate cities usually range from 11 to 14 hours, depending on the layover."
      },
      "q2": {

      },
      "q4": {
        "question": "When is the cheapest time to fly from London to Illinois?",
        "answer": "The cheapest time to fly from London to Illinois is typically in the off-peak months of January, February, and November, avoiding summer and the December holiday season. For the best fares, book at least two to three months ahead, fly midweek (Tuesday or Wednesday), and choose red-eye or early-morning departures, as peak holiday periods and school vacations drive prices higher."

        "question": "How far in advance should I book flights from London to Illinois?",

Springfield offers Lincoln history via Abraham Lincoln Capital Airport, while the Shawnee National Forest attracts nature lovers through regional airports like Williamson County. Your airport choice depends on whether you're exploring the city, history or outdoors."
      },
      "q7": {
        "question": "Do I need a passport or visa to travel from London to Illinois?",
        "answer": "For British citizens travelling from London to Illinois, no visa is required for a short tourist visit. Entry is visa-free for stays of up to 90 days, but you must obtain an ESTA electronic travel authorisation before travel.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",
