The most expensive months are December, June, and May, with average fares climbing to $2,078, $1,994, and $1,857.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Houston to Kolkata?", "answer": "For flights from Houston to Kolkata, the optimal booking window is 13 to 16 weeks before departure, with an average fare around $1,643. The cheapest single fare observed is $1,610 at about 8 weeks out, but booking last minute can cost up to $1,855. For summer or holiday periods, it's wise to book even earlier, as fares typically rise and availability tightens.", "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.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Houston to Kolkata?", "answer": "No overnight (red-eye) flights are scheduled from Houston (HOU) to Kolkata (CCU) — there are no nonstop red-eyes, and no connecting itineraries whose long leg is a red-eye were found.", "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.", "toolsUsed": ["redeye_flights"]}, "q7": {"question": "Which airlines usually operate this route from Houston to Kolkata?", "answer": "There are no nonstop flights from Houston Hobby (HOU) to Kolkata (CCU).
