        "question": "What is the typical flight duration from Madrid to London?",
        "answer": "A nonstop flight from Madrid (MAD) to London typically takes 2 hours 25 minutes to 2 hours 35 minutes. Most direct flights are operated by airlines like Iberia and British Airways, with minimal variation in flight time. The return trip from London to Madrid is similar, usually around 2 hours 20–30 minutes."
      },
      "q1": {
        "question": "Are there any direct flights from Madrid to London?",
        "answer": "Yes, there are plenty of non‑stop flights from Madrid to London. Iberia (IB) and British Airways (BA) both serve Heathrow daily with roughly 10–12 departures each, while easyJet (U2) flies to Luton and Gatwick daily, and Iberia Express (I2), Iberia (IB), Air Europa (UX), and Wizz Air UK (W9) also operate daily non‑stops to Gatwick or Luton. Ryanair (FR) flies to Stansted on Wednesdays through Sundays, and Ryanair UK (RK) operates on Mondays and Fridays only.",
        "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service and weekly frequencies are summarized from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

      "q2": {
        "question": "Are there visa requirements to travel from Madrid to London?",
        "answer": "Yes, there are visa or travel-authorization requirements for travel from Madrid to London. If you are a Spanish or other EU/EEA national, you currently do not need a visa for short visits (tourism, business, etc.) but from April 2, 2025, you will require a UK Electronic Travel Authorization (ETA). If you are a British national, you do not need a visa or ETA for entry into the UK. For non-EU/EEA and non-British nationals, whether you need a visa depends on your nationality; many nationalities require a visa, while some can apply for an ETA instead if eligible. When traveling from London back to Madrid, British nationals can enter Spain visa-free for short stays (up to 90 days in any 180-day period)."
      },
      "q6": {
        "question": "Are overnight (red‑eye) flights available from Madrid to London?",
        "answer": "Yes, overnight red‑eye flights are available from Madrid to London. British Airways departs Madrid for Heathrow at 21:06 five nights a week (Wednesday through Sunday), easyJet flies to Luton at 21:35 on Wednesdays and 22:20 on Sundays, and Ryanair UK operates a Friday service to Stansted at 22:30. These are short flights that land the same night rather than the next morning.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

        "answer": "Nonstop flights from Madrid to London are operated by Iberia, British Airways, easyJet, Ryanair, and several other carriers, with departures to Heathrow, Gatwick, Luton, and Stansted. Iberia and British Airways dominate the Heathrow route, offering roughly 66 and 60 weekly flights respectively, with median fares around $316 and $292. easyJet is the leading low-cost option, serving both Luton and Gatwick with up to 32 weekly flights combined. Air Europa also flies to Gatwick with 14 weekly flights and a median fare around $187, while Ryanair operates 14 weekly flights to Stansted.

        "question": "How reliable are on‑time departures on this route from Madrid to London?",
        "answer": "On‑time departures on Madrid to London flights are generally reliable, but afternoon and evening flights can face delays due to air traffic congestion. Early morning flights, particularly on Iberia and British Airways, tend to have the best on‑time performance."

        "answer": "Heathrow is the main international hub with the most connections and is well‑linked to central London. Gatwick serves many low‑cost and leisure flights, while City Airport is closest to the financial district and ideal for business travellers."
      },
      "q14": {
        "question": "Are there hotels or sleeping facilities at London airport?",
