Both airlines fly the route daily, so you can find a non‑stop any day of the week.",
        "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.",

        "question": "What are the ground transportation options in London?",

Taxis and ride-share services provide door-to-door convenience but can be expensive and subject to traffic delays. Coaches and local buses are available but slower. Car rentals are an option but not recommended for central London travel due to congestion and parking difficulties. Most travelers use rail services, with the Heathrow Express being the most popular for its speed and reliability."
