        "answer": "From Franjo Tuđman Airport, the fastest option is a taxi, with a fixed maximum fare of €35 to the city center (about 16 km). The Pleso Prijevoz shuttle bus connects the airport to the main bus station, and public bus line 290 links to Eugen Kvaternik Square via Velika Gorica. Ride-share services like Uber and Bolt are widely available and often slightly cheaper than taxis, while several car rental agencies operate at the airport. The shuttle bus is the most-used option for budget-conscious travelers, but taxis and ride-shares are preferred for door-to-door convenience.",

Air France offers a connection via Paris about once a day. Typical per-carrier fares are not provided for this route, so only the carriers and frequencies are listed.",
        "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 Denver Intl Airport from the city center?",
        "answer": "The fastest and most popular way from downtown Denver to Denver International Airport is the RTD A Line commuter train, which runs directly from Denver Union Station to the airport transit center in about 37 minutes. Ride‑share services like Uber and Lyft, as well as taxis, offer door‑to‑door convenience at a higher cost, while driving yourself and parking on‑site is widely available but can be pricey for longer trips. Several regional bus routes also serve the airport, but the train is generally the cheapest and most reliable option.",
