        "question": "What is the typical flight duration from Chicago to Colombo?",
        "answer": "No nonstop flights are scheduled between Chicago and Colombo; the journey requires at least one connection. The straight-line distance is about 8,970 miles, and a typical one-stop journey takes roughly 20 to 24 hours in total, depending on the layover and routing.",
        "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.",

        "answer": "There are no non‑stop flights from Chicago to Colombo. The shortest one‑stop routing is with Qatar Airways via Doha, where the long leg takes about 13 h 20 m and the second leg about 4 h 55 m, for a total journey of roughly 21–22 hours including the layover. Etihad via Abu Dhabi is another option, with a similar total duration.",

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.",

        "answer": "For United States citizens, a visa is not required for a short tourist visit to Sri Lanka, and the permitted length of stay is 30 days. However, an electronic travel authorization (ETA) must be obtained before travel.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

Car rental is available but less common for first-time visitors due to traffic and driving norms. The train is cheap but runs on a limited schedule, while taxis and ride-hailing offer door-to-door convenience at a higher price.",

        "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.",

Qatar Airways operates the most frequent pattern with about 18 daily connections through Doha, while Etihad offers around 8 via Abu Dhabi and Turkish Airlines about 2 via Istanbul. A less common option pairs Qatar Airways on the first leg with SriLankan Airlines on the second, also connecting in Doha.",

        "answer": "Bring a passport valid for at least six months beyond your arrival date, a Sri Lanka visa or ETA obtained before travel, proof of onward or return travel, and a payment method for baggage. No domestic ID is required as this is an international trip."

        "question": "Which airport should I use in Colombo?",
        "answer": "Colombo has one main airport, Bandaranaike International Airport, which handles all international flights. It is located about 35 kilometres north of downtown Colombo."
      },
      "q13": {
        "question": "How do I get to Dupage County from the city center?",
        "answer": "DuPage Airport (DPA) in West Chicago is a general aviation airport with no scheduled passenger service, so public transportation options to it from downtown Chicago are very limited; there is no direct CTA train, and Pace suburban bus routes do not reach the airport. Most travelers reach DPA by private car or taxi/ride-share, with driving via I-290 or I-88 being the most practical option, and on-site parking is generally plentiful. Taxis and ride-shares are available but can be costly for the roughly 30-mile trip from the city center. There are no dedicated airport shuttle buses from downtown to DPA.",
