        "question": "What is the typical flight duration from Houston to Calgary?",
        "answer": "A nonstop flight from Houston (IAH) to Calgary (YYC) typically takes about 4 hours 15 minutes. Return flights from Calgary to Houston often take slightly longer, around 4 hours 30 minutes, due to headwinds. With a layover, total travel time commonly ranges from 6 to 8 hours depending on the connection city."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to Calgary?",
        "answer": "Yes, there are direct non‑stop flights from Houston (IAH) to Calgary (YYC) on two airlines: WestJet (WS) and United (UA). Both operate daily, with WestJet offering up to six departures a day and United offering three, giving travelers a combined total of around nine daily non‑stop options.",
        "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 Houston to Calgary?",
        "answer": "Yes, visa or travel authorization requirements apply for a flight from Houston to Calgary depending on your nationality. U.S. citizens do not need a visa for tourist visits to Canada but must obtain an Electronic Travel Authorization (eTA) before flying, unless traveling with a valid U.S. visa and entering by air. Canadian citizens do not need a visa or eTA to enter Canada. If you are a national of another country, you may need a visitor visa or an eTA to enter Canada; check your specific nationality against Canada's entry requirements. Also, when returning from Calgary to Houston, U.S. citizens re-entering the U.S. do not need a visa, but foreign nationals must meet U.S. entry requirements, which may include a visa or ESTA under the Visa Waiver Program."

        "question": "What are the ground transportation options in Calgary?",
        "answer": "Calgary International Airport (YYC) is located about 17 kilometers northeast of downtown Calgary. Ground transportation options include taxis, ride-share services like Uber and Lyft, public transit, car rentals, and hotel shuttles. Taxis and ride-shares are convenient and available at the arrivals level, taking about 20 to 25 minutes to downtown, with fares typically between CAD 40 and 50. Public transit is provided by Calgary Transit's Route 300 Airport/BRT, which connects the airport to the city center in approximately 30 to 40 minutes for a lower fare, making it a cost-effective option. Car rentals are available on-site for those planning regional travel, but parking downtown can be expensive. The most used option for visitors is ride-share due to its balance of convenience, availability, and cost compared to taxis."

        "question": "When is the cheapest time to fly from Houston to Calgary?",
        "answer": "The cheapest months to fly from Houston to Calgary are October (averaging $394), August ($419), and September ($425), with the low season spanning October, August, September, and November. The most expensive months are December ($555), February ($521), and June ($520), with high season covering January, June, February, and December.",
        "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 Houston to Calgary?",
        "answer": "For flights from Houston to Calgary, the optimal booking window is roughly 21 to 24 weeks before departure, with average fares around $401. During summer and holiday periods, demand can push prices higher, so booking even earlier—closer to 24 weeks ahead—is advisable to secure the best rate.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Houston to Calgary?",
        "answer": "There are no nonstop red-eye flights from Houston (IAH) to Calgary (YYC). Connecting itineraries with an overnight leg do exist — for example, via Toronto (YYZ) where the YYZ→YYC leg on Air Canada departs around 11:05 PM and arrives around 1:21 AM, or via Montreal (YUL) with a YUL→YYC leg departing around 9:10 PM and arriving near 11:52 PM — but these require a long layover and a connecting flight from Houston 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.",

WestJet runs about 38 weekly flights with typical fares around $591, while United offers around 28 weekly flights with a median fare near $530.

Dallas offers a short first leg and multiple daily frequencies. Seattle provides a geographically logical stop with good onward schedules to Calgary.

Real ID is not applicable for this international route."

        "question": "How do I get to George Bush Intercontinental Airport from the city center?",
        "answer": "From downtown Houston to IAH, the METRO 102 bus is the main public transit option, taking about 50–70 minutes and is the least expensive. Shared shuttles, rideshares, and taxis are faster, typically 25–35 minutes without traffic, but cost more. Driving and parking on-site is available, with economy lots being the most affordable but less convenient than terminal garages."
