        "answer": "Flights from Bengaluru to Chicago arrive primarily at O'Hare (ORD) or Midway (MDW). From O'Hare, the CTA Blue Line 'L' train is the fastest and most-used option, reaching downtown in about 45 minutes for $5; taxis and ride shares offer door-to-door service in 30–60 minutes for $40–60. Midway is connected by the CTA Orange Line in about 25 minutes for $2.50, with similar taxi and ride share availability. Both airports have on-site car rental facilities, though driving into the city can be congested. For the general aviation DuPage Airport, ground transport is limited to taxis, ride shares, or rental cars, with no direct mass transit to the city center.",

        "question": "When is the cheapest time to fly from Bengaluru to Chicago?",
        "answer": "On the Bengaluru to Chicago route, the cheapest months to fly are September, October, and February, with average fares around $417, $425, and $431 respectively. The most expensive months are December, June, and July, where average fares climb to roughly $517, $492, and $485.",
        "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly. 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.",

        "question": "How far in advance should I book tickets from Bengaluru to Chicago?",
        "answer": "For flights from Bengaluru to Chicago, the optimal booking window is roughly 4-6 weeks before departure, with the very best fares around 35 days out averaging $353. Booking more than 3 months ahead tends to cost more, rising to about $551 at 6 months out, and last-minute bookings within 2 weeks also climb above $400.",
        "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window.

        "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.",

Abu Dhabi provides streamlined US pre-clearance. Frankfurt allows direct entry to the US on arrival, often with shorter total travel time."

        "question": "Which airport should I use in Chicago?",
        "answer": "O'Hare is the main international gateway, about 17 miles northwest of downtown, with extensive global connections and a hub for United and American. Midway is closer to the city centre and mainly serves domestic low‑cost carriers like Southwest."
      },
      "q13": {
        "question": "How do I get to Kempegowda Intl Airport from the city center?",
        "answer": "From Bengaluru city center, the most popular and reliable option is the Vayu Vajra air-conditioned bus service run by BMTC, with frequent departures from key points like Majestic and Electronic City. Ride-share and taxi services such as Ola and Uber operate freely to the airport, offering door-to-door convenience at a higher cost, while driving yourself is possible with both short-term and long-term parking available at the terminal. A suburban train service runs six days a week from the city to the Kempegowda International Airport Halt station, where a free shuttle completes the journey, providing a low-cost alternative. The Vayu Vajra buses are considered the fastest and most cost-effective choice for most travelers, though taxis and ride-shares are preferred for comfort or heavy luggage.",

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.",

In Terminal 2, the 080 International Lounge is available after security for international passengers, accessible to business class travelers and Priority Pass members, with showers and a selection of food and drinks. Terminal 1 has the 080 Domestic Lounge for domestic flyers, while the T1 Lounge (Kerbside) is open 24 hours before security. The 080 Arrival Lounge in Terminal 2 serves international arrivals, and there's also a BLR Domestic Lounge in Terminal 1. Eligibility varies by lounge, with many accepting Priority Pass or day passes, though some like the 080 International Lounge may restrict access to certain airlines' premium passengers.",
