        "question": "What is the typical flight duration from Chennai to Washington?",
        "answer": "Chennai to Washington requires a connection, as there are no nonstop flights on this route. The distance is about 8,565 miles, and a typical one-stop journey takes approximately 20 to 24 hours depending on layovers.",
        "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 Chennai to Washington?",
        "answer": "There are no nonstop flights from Chennai (MAA) to Washington, D.C. (WAS). The shortest one-stop connections are on Etihad via Abu Dhabi (about 21.5 hours total, with a 4.5-hour first leg and a 14.5-hour second leg) or on Emirates via Dubai (roughly 20.5 hours, with a 4-hour first leg and a 14.5-hour second leg). Lufthansa also offers connections via Frankfurt, but with a longer overall journey.",
        "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold. 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 Washington?",
        "answer": "Ronald Reagan Washington National Airport (DCA) offers Metrorail directly from a station connected to Terminals B and C, providing fast and affordable access to downtown Washington, D.C. Ride-share services like Uber and Lyft have designated pickup zones, and taxis, rental cars, and sedan or limousine services with pre-arranged reservations are also available. The Metrorail is the most-used option for reaching the city center because it is direct, inexpensive, and avoids traffic. Car-sharing via Turo and off-airport shuttle buses, including local Metrobus route 5A to downtown, add further choices, but the Metrorail is generally the fastest and most popular for most travelers.",

        "answer": "Washington has three airports. Dulles is the main international gateway, about 42 km west of downtown, and a major United hub. Reagan National is closest to central Washington, just across the Potomac, but handles mostly domestic flights and a few international routes. Baltimore/Washington International is further out, about 48 km northeast, and serves as a base for Southwest and low‑cost carriers."

        "answer": "Getting to Chennai International Airport from the city center is easiest via the Chennai Metro, which has a dedicated airport station and is the fastest, most popular option. Ride‑share services like Uber and Ola, as well as taxis, offer door‑to‑door convenience at a higher cost. The Tirusulam suburban railway station also serves the airport for budget‑minded travelers, and driving is possible with paid parking available at the terminal.",
