        "question": "What is the typical flight duration from Austin to Lisbon?",
        "answer": "There are currently no nonstop flights from Austin (AUS) to Lisbon (LIS). With one stop, total travel time typically ranges from 10 to 14 hours, depending on the layover duration. Common connecting cities include New York (JFK), Newark (EWR), and London (LHR)."

        "question": "Are there visa requirements to travel from Austin to Lisbon?",
        "answer": "Yes, visa requirements apply for travel between Austin and Lisbon. U.S. citizens can enter Portugal and the Schengen Area for up to 90 days within any 180-day period without a visa for tourism or business, but from 2025 will need an ETIAS authorization. Portuguese citizens traveling to the U.S. must have a valid visa or an ESTA authorization under the Visa Waiver Program. Other nationals should check both U.S. and Schengen entry rules based on their citizenship."

        "question": "What are the ground transportation options in Lisbon?",
        "answer": "From Lisbon Airport, the Aerobus shuttle is the most popular and reliable option, reaching the city center in 20–25 minutes for €4 (24-hour pass). Public buses (routes 5, 22, 44, 45, 83) are cheaper but slower. Taxis are available at ranks with a metered fare plus an airport surcharge. There is no direct train, but nearby metro stations (e.g., Oriente) are a short taxi ride away. Ride-share and car rentals are also available, though the Aerobus is the most used and fastest direct public transit.",

        "question": "When is the cheapest time to fly from Austin to Lisbon?",
        "answer": "The cheapest months to fly from Austin to Lisbon are April, November, and October, with average round-trip fares as low as $860–$902. The most expensive months are June, July, and May, where prices peak around $1,422.",
        "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.",

      "q5": {
        "question": "How far in advance should I book tickets from Austin to Lisbon?",
        "answer": "For flights from Austin to Lisbon, booking 11 to 14 weeks ahead typically yields the best fares, averaging about $881. The lowest single-day price appears around 90 days before departure at $868, while prices rise noticeably beyond 125 days out. For peak summer or holiday travel, booking even earlier is wise, as last-minute fares can spike above $1,000.",
        "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.",

        "answer": "No nonstop red-eye flights operate from Austin to Lisbon, but several one-stop connecting itineraries include an overnight long leg. From Austin itself, KLM offers a red-eye departure at 6:05 PM via Amsterdam arriving at 10:30 AM the next morning, while British Airways has a 5:55 PM departure via London Heathrow arriving at 9:15 AM. Other connecting red-eyes are available from nearby U.S. gateways: American departs Philadelphia at 9:05 PM arriving Lisbon at 9:05 AM, United departs Washington Dulles at 10:25 PM arriving at 10:30 AM, and United also offers a Newark departure at 8:25 PM arriving at 8:20 AM.",
        "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": "Which airlines usually operate this route from Austin to Lisbon?",
        "answer": "There is no nonstop service from Austin to Lisbon. Common one‑stop routings include British Airways via London Heathrow (around 11 daily connections), United via Washington Dulles or Newark (5 and 1 daily respectively), American via Philadelphia (5 daily), Air Canada via Toronto (3 daily), KLM via Amsterdam (2 daily), and TAP Air Portugal via Fort Lauderdale or Miami (2 and 1 daily). No per‑carrier fares are available for this route.",

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.",

        "question": "If I need a connection, what are common layover cities between Austin and Lisbon?",
        "answer": "Common layovers include New York JFK, Newark, Boston, and Philadelphia, which provide efficient connections and keep total travel time competitive. These U.S. hubs offer broad domestic feed, streamlined transfers, and avoid international transit visa requirements for this route."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Austin to Lisbon?",
        "answer": "On-time reliability is generally good, though afternoon thunderstorms in Austin can cause delays. Early morning departures on carriers like Delta or United are your best bet for staying on schedule."

        "question": "What documents should I bring with me to the airport when flying from Austin to Lisbon?",
        "answer": "Bring a passport valid for at least three months beyond your stay, proof of onward or return travel, and a payment method for bags. U.S. citizens do not need a visa for short stays, but starting in 2025 an ETIAS authorization will be required. No vaccination certificates are currently required."
      },
      "q12": {
        "question": "Which airport should I use in Lisbon?",
        "answer": "Lisbon has only one airport, Humberto Delgado Airport, located about 7 km from the city centre and serving all flights."
      },
      "q13": {
        "question": "How do I get to Bergstrom Intl Airport from the city center?",
        "answer": "From downtown Austin, you can reach Austin-Bergstrom International Airport (AUS) via public bus (Capital Metro Route 20, the most affordable option), ride-share services like Uber and Lyft (fastest and most popular), taxis, shared shuttle vans, or driving and parking on-site. The bus takes about 30–40 minutes and costs a few dollars, while ride-shares and taxis take 15–25 minutes at a higher fare. Driving and parking in the airport garages or economy lots is convenient but costs vary by duration; a free cell phone lot is available for pickups.",
