        "answer": "London offers extensive ground transportation from its airports to the city center.

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."
