        "question": "What is the typical flight duration from Washington to Chennai?",
        "answer": "There is no nonstop service from Washington (IAD) to Chennai (MAA); the route is about 8,570 miles and requires at least one connection. A typical one-stop journey takes approximately 20 to 24 hours, depending on the layover.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Washington to Chennai?",
        "answer": "There are no nonstop flights from Washington Dulles to Chennai. The shortest one-stop itineraries connect via Doha on Qatar Airways (about 16–17 hours total), Frankfurt on Lufthansa (roughly 17–18 hours), or Abu Dhabi on Etihad (around 17–18 hours), with several departures available on a typical day.",
        "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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.",

        "question": "What are the ground transportation options in Chennai?",
        "answer": "Chennai International Airport is about 21 km southwest of the city center and is directly served by the Chennai Metro via the Airport Metro Station, which is generally considered the most used and reliable option for getting downtown. A suburban rail connection at Tirusulam station also links to the wider Chennai Suburban Railway network, providing an alternative mass transit choice. Taxis and ride-share services are readily available at the terminals and offer the fastest door-to-door travel, though they are more affected by road traffic than the metro. Car rentals are present but less commonly used by visitors for central Chennai trips given the strong public transit links.",

        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

Dubai and Doha offer efficient single‑stop itineraries with strong onward connections to Chennai, plus visa‑free transit for most passport holders. London and Frankfurt provide broad one‑stop options via major European hubs, though transit visas may be required for some nationalities; confirm based on your passport."

        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "You can reach Washington Dulles International Airport from downtown Washington, D.C. by taking the Washington Metro's Silver Line directly to the airport station, which is connected to the main terminal via an indoor pedestrian tunnel with moving sidewalks. Ride-share services, taxis, and shuttle buses also serve the airport, and driving is possible with on-site parking garages. The Metro is generally the most popular and economical option for avoiding traffic, while taxis and ride-shares offer door-to-door convenience at a higher cost.",
