        "question": "What is the typical flight duration from Dhaka to Singapore?",
        "answer": "A direct flight from Dhaka (DAC) to Singapore (SIN) typically takes around 4 hours to 4 hours and 15 minutes. Flights with one stop, often via Kuala Lumpur or Bangkok, usually take between 7 and 9 hours total. The return flight from Singapore to Dhaka is similar in duration, with direct flights also around 4 hours. Biman Bangladesh Airlines and Singapore Airlines offer direct services, while Malaysia Airlines and Thai Airways are common choices for connecting flights."
      },
      "q1": {
        "question": "Are there any direct flights from Dhaka to Singapore?",
        "answer": "Yes, there are nonstop flights from Dhaka (DAC) to Singapore (SIN) operated by Singapore Airlines, Biman Bangladesh Airlines, and US-Bangla Airlines, all running daily. Singapore Airlines flies twice daily (departing around 4:00 PM and 11:55 PM), while Biman departs at 8:25 AM and US-Bangla at 10:30 PM.",
        "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. Carrier service and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "Are there visa requirements to travel from Dhaka to Singapore?",
        "answer": "Yes. Bangladeshi citizens require a visa to enter Singapore. They must apply for an e‑visa or a visa through an authorized agent before travel, unless they hold a valid long‑term pass from certain countries. Singapore citizens traveling to Bangladesh need a visa, which can be obtained on arrival for tourism if arriving at Dhaka airport, or in advance from a Bangladeshi diplomatic mission. Visa requirements for other nationalities depend on their passport. Always check the latest rules with the relevant embassy before flying."

      "q3": {
        "question": "What are the ground transportation options in Singapore?",
        "answer": "Singapore Changi Airport offers excellent ground transportation to the city center. The MRT mass rapid transit system is the most popular choice, with stations at Terminals 2 and 3 accessible by foot and via a free Skytrain from Terminals 1 and 4. The ride to central areas like City Hall takes about thirty-five to forty minutes and is clean, reliable, and affordable. Public buses are a cheaper alternative but slower and less convenient with luggage. Taxis and ride-share services like Grab are widely available, offering a door-to-door journey of about twenty to thirty minutes depending on traffic, though at a higher cost. Car rentals are available at the airport but are not recommended for city travel due to high costs, limited parking, and excellent public transport. The MRT is the most used option for its efficiency and value."
