Approximate total travel time is around 20 to 24 hours, depending on the layover. The airports are about 8,360 miles apart.", "methodology": "Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": ["flight_schedule"]}, "q3": {"question": "What are the ground transportation options in Houston?", "answer": "At George Bush Intercontinental Airport (IAH), you can get to downtown Houston (about 23 miles south) by rental car, ride share (Uber/Lyft), taxi, shuttle, limousine, or public bus. The most-used options are ride shares and rental cars; ride shares are usually the fastest door‑to‑door, while the 500 IAH Downtown Direct bus provides an economical public‑transit connection. Taxis are available 24/7 at Terminals A, C, and E, and hotel shuttles can be requested from baggage claim. Car rentals are consolidated at a center a five‑minute shuttle ride from the terminals.", "toolsUsed": [], "references": [{"url": "https://fly2houston.com/iah", "title": "IAH Houston Airport | George Bush Intercontinental", "time_published": "2026-06-23T05:00:00Z"}, {"url": "https://fly2houston.com/iah/ground-transportation/", "title": "Ground Transportation | Airport Taxi, Uber, Lyft, Shuttle & Rent Car Houston", "time_published": "2026-01-23T19:44:20Z"}, {"url": "https://en.wikipedia.org/wiki/George%20Bush%20Intercontinental%20Airport", "title": "George Bush Intercontinental Airport", "time_published": "2026-05-01T12:20:43Z"}, {"url": "https://en.wikipedia.org/?diff=597698305", "title": "George Bush Intercontinental Airport: Difference between revisions - Wikipedia", "time_published": "2014-03-01T18:21:06Z"}, {"url": "https://faa.gov/regulations_policies/orders_notices/index.cfm/go/document.information/documentID/1023367", "title": "Notice JO 7110.659 - Non-Intersecting Converging Runway Operations for George Bush Intercontinental/Houston Airport Traffic Control Tower and Houston Intercontinental Terminal Radar Approach Control (", "time_published": "2026-04-10T00:00:00Z"}]}, "q4": {"question": "When is the cheapest time to fly from Delhi to Houston?", "answer": "The cheapest months to fly from Delhi to Houston are September, October, and August, with average fares around $1,084 to $1,153. The most expensive months are December, June, and July, where average fares climb to roughly $1,333 to $1,473.", "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Delhi to Houston?", "answer": "For flights from Delhi to Houston, the best fares are typically found when booking 10 to 13 weeks ahead, with an average price of $1,249 in that window. Booking around 90 days out can yield the lowest fares, around $1,236, while last-minute tickets can cost over $1,600. During peak summer or holiday periods, demand may push optimal booking slightly earlier, so aiming for 12 to 16 weeks ahead is prudent.", "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Delhi to Houston?", "answer": "No nonstop red-eye flights operate from Delhi to Houston, but connecting itineraries whose long leg is an overnight flight are available.

From Toronto you connect onward to Houston on either Air Canada or United after a layover of about 2 hours 50 minutes.", "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 Delhi to Houston?", "answer": "There are no nonstop flights from Delhi to Houston.
