        "question": "What is the typical flight duration from London to Washington D.C.?",
        "answer": "A nonstop flight from London to Washington D.C. (Dulles, IAD) takes about 8 hours 30 minutes westbound. The return flight eastbound is notably shorter at around 7 hours due to favorable jet stream winds. With a layover, typically through New York or another European hub, total travel time rises to 11 to 13 hours. British Airways and United operate the most frequent nonstop service on this route."

        "question": "What are the ground transportation options in Washington D.C.?",
        "answer": "Washington D.C. is served by three airports. Dulles International (IAD) connects to downtown via the Silver Line Metro in about an hour, a major improvement over the previous bus-only options. Reagan National (DCA) is the most convenient, with a Metro station on the Blue and Yellow lines reaching downtown in fifteen to twenty minutes, making it the preferred airport for city travelers. BWI Airport connects via MARC and Amtrak trains to Union Station in roughly thirty minutes, plus shuttle buses to the rail station. Taxis and ride-share services like Uber and Lyft are widely available at all three airports but can be costly and slow in traffic. Car rentals are available at each airport and suit regional travel well. Metro is the most commonly used option overall, and flying into Reagan National maximizes convenience since the Metro stop is directly connected to the terminal."
