The shortest connecting itineraries take around 21 hours and 20 minutes, typically via Doha (DOH) with Qatar Airways, or via Toronto (YYZ) with Air Canada, among others. One-stop fares start around $1,017, and a red‑eye option exists on the outbound leg from Houston to Frankfurt with United, connecting to Lufthansa on to Delhi.", "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. 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. 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. Stop counts, connecting hubs, and per-airline prices are drawn from a large sample of the real fares Priceline users found on this route in the last 72 hours. We group those fares by number of stops, by the hub airport a connection routes through, and by operating airline, and report each group's share of the sample alongside its lowest and median price. 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. The US departure cities with nonstop service to this destination, their weekly flight frequencies, typical flight times, airlines, and red-eye availability 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 identify every US airport with scheduled nonstop service to the destination, group them into their metropolitan areas, and rank the cities by scheduled weekly departures; the typical flight time is the median scheduled duration, and red-eye availability is flagged from scheduled local departure and arrival times.", "toolsUsed": ["route_airlines", "flight_schedule", "route_options", "redeye_flights", "country_to_city"]}, "q3": {"question": "What are the ground transportation options in Delhi?", "answer": "From Delhi's Indira Gandhi International Airport, the fastest option into the city center is the Airport Express Line of the Delhi Metro, which reaches New Delhi Railway Station in about 20 minutes. Prepaid taxis and app-based ride shares like Uber and Ola are widely available and offer door-to-door convenience, though travel time can vary with traffic. Air-conditioned DTC buses also connect to various parts of the city and are the most economical choice. The metro is the most-used public transit mode overall in Delhi, but for airport transfers, taxis and ride shares are extremely popular due to luggage and comfort. Car rentals are available but less common for city-center trips given the dense traffic and parking challenges.", "toolsUsed": [], "references": [{"url": "https://hongkongairport.com/sites/en/passenger-guide/overseas-airports-information/delhi.page", "title": "Delhi Indira Gandhi International Airport, Passenger Guide - Hong Kong International Airport", "favicon": "https://hongkongairport.com/iwov-resources/image/common/icon/favicon.ico"}, {"url": "https://en.wikipedia.org/wiki/Indira%20Gandhi%20International%20Airport", "title": "Indira Gandhi International Airport", "time_published": "2026-05-01T11:11:01Z"}, {"url": "https://www.civilaviation.gov.in/taxonomy/term/180", "title": "Indira Gandhi International Airport, Delhi | Ministry of Civil Aviation", "time_published": "2026-03-30T10:57:53Z"}, {"url": "https://en.wikipedia.org/wiki/Transport_in_Delhi", "title": "Transport in Delhi", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-06-07T13:07:46Z"}, {"url": "https://hongkongairport.com/en/transport/to-from-airport/index.page", "title": "Overview, To and From Airport - Hong Kong International Airport", "favicon": "https://hongkongairport.com/iwov-resources/image/common/icon/favicon.ico"}]}, "q4": {"question": "When is the cheapest time to fly from Houston to Delhi?", "answer": "The cheapest months to fly from Houston to Delhi are September (average $1084), October ($1128), and August ($1153), which fall in the low season. The most expensive months are December (average $1473), June ($1446), and July ($1333), during the high season.", "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 Delhi?", "answer": "For flights from Houston to Delhi, the best fares are typically found when booking 10 to 13 weeks before departure, with an average price around $1,249 in that window. The absolute lowest single fare appears at about 90 days out at $1,236, while last-minute bookings can cost over $1,600. For summer and holiday periods, aiming for the earlier end of that window or even slightly beyond can help avoid price spikes.", "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 Delhi?", "answer": "There are no nonstop red‑eye flights from Houston (IAH) to Delhi (DEL), but connecting itineraries whose long leg is an overnight red‑eye do exist.

The fastest and most popular option is a ride‑share (Uber or Lyft) or a taxi, taking roughly 30 minutes without traffic; taxis have a fixed fare to downtown. A direct bus, route 102, also operates from downtown, offering a low‑cost alternative that takes longer.
