        "answer": "Vienna International Airport offers several ground transportation options to the city center. The City Airport Train (CAT) is the fastest, reaching Wien Mitte in about 16 minutes, though it is currently operating with buses due to railway maintenance and is expected to resume train service in November 2027. The S-Bahn line S7 provides a cheaper local train option, taking approximately 25 minutes to the city center, and long-distance Railjet trains connect the airport to Vienna Main Station in about 15 minutes. Taxis, car rentals, and buses are also available at the airport. The S-Bahn and City Airport Train are the most commonly used public transit options for reaching central Vienna.",

Lufthansa operates the most, with late-afternoon departures from Denver to Munich (4:15 PM, arriving 10:00 AM) or Frankfurt (5:40 PM, arriving 11:15 AM), connecting onward to Austrian Airlines; British Airways offers a 6:40 PM departure to London arriving 10:35 AM, and Air France has a 5:40 PM departure to Paris arriving 11:10 AM. Austrian Airlines also offers a true late-evening red-eye from Newark (JFK at 9:45 PM, arriving 11:55 AM) with a United connection from Denver, though that requires a domestic hop first.",
        "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.",

        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "From downtown Denver, the RTD A Line train runs every 15 minutes, 24/7, and reaches the airport in about 37 minutes for a budget-friendly fare, departing from Union Station. Ride-share services like Uber and Lyft, along with taxis, take roughly 25–35 minutes and offer door-to-door convenience at a higher cost, while shared vans are slower at 45–60 minutes but work well for hotel drop-offs. Driving yourself is also an option with on-site parking, though the airport is about 25 miles northeast of downtown and parking adds to the overall cost. The A Line is the most popular choice for travelers seeking a reliable, low-cost connection, while ride-share is fastest for those prioritizing convenience.",
