        "question": "What is the typical flight duration from Delhi to Houston?",
        "answer": "No nonstop flights operate between Delhi and Houston, so the journey requires at least one connection. Approximate total travel time is around 20 to 24 hours, depending on the layover. The airports are about 8,360 miles apart.",
        "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.",

The most-used and fastest option to downtown is the METRO 500 IAH Downtown Direct bus, which runs every 30 minutes from Terminal E to the George R. Brown Convention Center for just $4.50 one way, seven days a week from 5:30 a.m. to 8 p.m. Ride share and taxis are convenient for door-to-door trips, while rental cars require a short shuttle to the Rental Car Center.",

The overnight leg departs Delhi at 22:50 on Air Canada, arriving in Toronto at 05:30 — that's early morning the next day. From Toronto you connect onward to Houston on either Air Canada or United after a layover of about 2 hours 50 minutes.",
        "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.",

Other connecting carriers with daily or near‑daily service are Lufthansa via Frankfurt, United via Munich or Frankfurt, and ANA via Tokyo Haneda. Per‑carrier median fares are not available for this route.",
        "methodology": "Airlines and weekly frequencies 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). 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 typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.",

      },
      "q13": {
        "question": "How do I get to Indira Gandhi Intl Airport from the city center?",
        "answer": "From central Delhi, the Delhi Metro is the most popular and often fastest option, with the Airport Express Line connecting New Delhi station to the airport in about 20 minutes, while regular DTC buses provide cheaper but slower service. Ride-sharing apps like Uber and Ola, along with radio taxis and auto-rickshaws, offer door-to-door convenience at a higher cost, and driving yourself is possible with paid parking at the terminals. Taxis and ride-shares are generally faster than buses but can be affected by traffic, while the metro is the most reliable for avoiding congestion.",
