        "question": "What is the typical flight duration from London to Baltimore?",
        "answer": "The flight from London Heathrow to Baltimore is about 3,630 miles and typically takes 8 hours 15 minutes. The return leg is shorter at 7 hours 20 minutes, a difference of 55 minutes due to prevailing winds.",
        "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.",

The free BWI Marshall Airport Shuttle connects to the BWI Rail Station for MARC and Amtrak trains, with MARC providing a quick 30-minute ride to Baltimore's Penn Station. The MTA Light Rail is also accessible via the shuttle or a short walk from the terminal, offering a direct route to downtown Baltimore in about 30 minutes. Taxis, ride-shares like Uber and Lyft, and rental cars are readily available 24/7, with driving times to the city center around 15-20 minutes. The MARC train and Light Rail are the most-used and fastest public transit options for getting into Baltimore.",

        "question": "When is the cheapest time to fly from London to Baltimore?",
        "answer": "September is the cheapest month to fly from London to Baltimore, with average fares around $374, followed by October at $380 and February at $399. December is the most expensive month at about $480, with July and June also on the pricier side at roughly $466 and $449 respectively.",
        "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 London to Baltimore?",
        "answer": "For flights from London Heathrow to Baltimore, the optimal booking window is about 4 to 6 weeks before departure, with average fares around $345. The single cheapest day to book is roughly 30 days out at $344, while booking much earlier (e.g. 5+ months ahead) tends to cost significantly more, around $480. For summer or holiday travel, it's usually wise to book at the earlier end of that window or even slightly sooner, as demand pushes prices up.",
        "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. Thin and international routes are neighbor-filled from the nearest dense routes, with the price level anchored to the route's own bookings. It reflects current fares and is refreshed monthly.

        "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.",

        "question": "Which airport should I use in Baltimore?",
        "answer": "Baltimore has one primary airport, Baltimore/Washington International Thurgood Marshall Airport (BWI), located about 10 miles south of downtown.

        "question": "How do I get to Heathrow Airport from the city center?",
        "answer": "From central London, the fastest option is the Heathrow Express train from Paddington Station, taking about 15 minutes; it’s the most popular for speed but is pricier. The Elizabeth line and Piccadilly line on the Tube offer cheaper, frequent services from various points, taking 30–55 minutes. National Express and RailAir coaches run from Victoria Coach Station and other hubs, while ride‑share and taxis provide door‑to‑door convenience at higher cost. Driving is possible but parking is expensive, so public transport is generally recommended.",
