        "question": "Are there visa requirements to travel from Washington D.C. to Istanbul?",
        "answer": "U.S. citizens traveling to Turkey must obtain a visa. The easiest option is an e-Visa, available at evisa.gov.tr, which allows stays of up to 90 days within a 180-day period for tourism or business. Turkish citizens traveling to the United States must obtain a U.S. visa from a U.S. embassy or consulate, as Turkey is not part of the Visa Waiver Program. Both nationalities should apply well in advance of travel."

        "question": "What are the ground transportation options in Istanbul?",
        "answer": "Istanbul Airport (IST) is located about 35 kilometers northwest of the city center, and several transport options connect the two. The metro M11 line links the airport directly to Gayrettepe, where it connects to the M2 line reaching Taksim and beyond, taking roughly 40 minutes total and being the fastest and most affordable option. Havaist airport buses serve multiple destinations across the city at low cost but take longer depending on traffic. Taxis are plentiful and metered but the journey can take 45 to 90 minutes depending on congestion, which is frequently severe. Uber and local ride-share apps operate in Istanbul and offer a convenient alternative to taxis. Car rentals are available at the airport and suit travelers heading beyond Istanbul. The metro is increasingly the most used option among savvy travelers due to its reliability and low cost, though many visitors still rely on taxis for door-to-door convenience."
