        "question": "What is the typical flight duration from Madrid to London?",
        "answer": "A nonstop flight from Madrid (MAD) to London takes about 2 hours 20 minutes westbound. The return flight from London to Madrid typically runs slightly shorter at around 2 hours 10 minutes due to favorable winds. Nonstop service is operated by British Airways, Iberia, and Vueling. Connecting flights via hubs like Paris or Amsterdam add 4 to 6 hours total travel time."
      },
      "q1": {
        "question": "Are there any direct flights from Madrid to London?",
        "answer": "Yes, there are plenty of nonstop flights from Madrid (MAD) to London — multiple airlines operate them daily to several London airports: Iberia (IB) and British Airways (BA) fly to Heathrow (LHR) daily with around 10–12 departures each per day, while easyJet (U2), Iberia Express (I2), Air Europa (UX), and European Air Charter (EA) serve Gatwick (LGW) daily, easyJet and Wizz Air (W9) also fly to Luton (LTN) daily, and Ryanair (FR) operates to Stansted (STN) on Wednesday through Sunday. In total there are well over 200 nonstop flights per week across all London airports, so you have a very wide choice of carriers, times, and terminals.",

As of January 8, 2025, EU nationals including Spanish citizens must obtain a UK Electronic Travel Authorization (ETA) before travel.

      "q3": {
        "question": "What are the ground transportation options in London?",
        "answer": "London offers extensive ground transportation from its airports to the city center. From Heathrow, the Heathrow Express train reaches Paddington Station in about fifteen minutes and is the fastest option. The Elizabeth Line and the Piccadilly Line on the Underground are slower but less expensive, taking around forty to fifty minutes. From Gatwick, the Gatwick Express reaches Victoria Station in about thirty minutes, while regular trains take longer. Stansted is linked to Liverpool Street Station by the Stansted Express in roughly forty-five minutes, and Luton connects to central London by the Luton DART and Thameslink services in under an hour. London City Airport is closest to the center, accessible by the Docklands Light Railway in about twenty minutes. Taxis and ride-share services are widely available but can be slow and costly in traffic. Coaches are cheaper but take longer, while car rentals are convenient for travel beyond London though less practical for city trips. Most travelers use rail services because they balance speed, reliability, and cost."

        "question": "Are overnight (red‑eye) flights available from Madrid to London?",

        "question": "If I need a connection, what are common layover cities between Madrid and London?",
        "answer": "Madrid to London is well served by direct flights taking around 2.5 hours, making connections unnecessary. If you prefer a connection, Paris Charles de Gaulle and Amsterdam Schiphol are common hubs with efficient transfers and broad onward connections, though they will add significant time to what is otherwise a short route."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Madrid to London?",
        "answer": "On-time performance on Madrid to London is moderate but inconsistent, as both Barajas and Heathrow rank among Europe's busier hubs and are prone to congestion-related delays. Flights into London City airport tend to run more punctually than Heathrow arrivals. Early morning departures on Iberia and British Airways historically show better on-time rates, so booking the first wave of the day reduces your risk meaningfully."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to London?",
        "answer": "May to June and September offer the best balance of mild temperatures, longer daylight hours, and fewer tourists than the busy July and August peak season."

        "question": "What documents should I bring with me to the airport when flying from Madrid to London?",
        "answer": "EU citizens can enter the UK with a valid national ID card or passport, though from 2025 the UK requires a valid passport for most travelers. Non-EU nationals may need a UK ETA, which launched in 2024. Bring proof of onward or return travel, a payment method for baggage fees, and no vaccination certificate is currently required for entry into the UK."

      "q12": {
        "question": "Which airport should I use in London?",

Luton suits budget travellers on easyJet and Wizz Air. City Airport is closest to the centre, ideal for business travellers on short-haul routes."

        "question": "How do I get to Adolfo Suárez Barajas Airport from the city center?",
        "answer": "From central Madrid, Metro Line 8 reaches Barajas in about 25 minutes and is the cheapest option, though a supplement applies for the airport zone. The Cercanias C-1 train is slightly slower but also affordable. Licensed taxis offer a flat-rate fare from the city center and are popular for convenience. Rideshares like Cabify and Uber are available at moderate cost. Driving and parking at the airport is possible but expensive for longer stays."
      },
      "q14": {
        "question": "Are there hotels or sleeping facilities at London airport?",
