        "question": "What is the typical flight duration from Baltimore to London?",
        "answer": "The flight from Baltimore to London covers about 3,630 miles. Nonstop service is available on British Airways, with a typical outbound time of 7 hours and 20 minutes. The return leg averages 8 hours and 15 minutes, making it about 55 minutes longer due to prevailing winds.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Baltimore to London?",
        "answer": "British Airways operates daily nonstop flights from Baltimore (BWI) to London Heathrow (LHR), with 22 departures per week. Departure times vary between roughly 7:25 PM and 9:35 PM, and the flight takes about 7 hours and 20 minutes eastbound.",
        "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.",

However, an electronic travel authorisation (ETA) must be obtained before travel, even though entry is visa-free.\n\nA quick note: this is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

        "question": "When is the cheapest time to fly from Baltimore to London?",
        "answer": "Average fares from Baltimore to London bottom out around $362 in late September, making it the cheapest stretch of the year to fly. The cheapest months overall are September ($374), October ($380), and February ($399), while the most expensive period is late December, when averages climb to about $507.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "question": "How far in advance should I book tickets from Baltimore to London?",
        "answer": "For flights from Baltimore to London, the best fares are typically found when booking 4–6 weeks ahead of departure, averaging around $345. The absolute cheapest single day to book is 30 days out at $344, while booking very early—say 160 days ahead—runs about $484, so you don't need to book months in advance. For summer and holiday periods, demand usually pushes the optimal window slightly earlier, so aim for 6–8 weeks out during those peak times.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. 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": "How do I get to Thurgood Marshall Intl Airport from the city center?",
        "answer": "Getting to BWI from downtown Baltimore is easy: the MTA Light Rail runs directly from the city center to the terminal, with trains every 10–15 minutes and a flat fare of $2.00 each way. Ride-share apps like Uber and Lyft drop off at the departures level, while taxis are available from local companies and are not allowed to charge flat rates. Driving yourself is also common, with on-airport parking lots and a free shuttle from the daily garage, express lot, and long-term lots to the terminal. The Light Rail is generally the most popular and cheapest option for solo travelers, while ride-share or taxis are faster and more convenient for those with luggage.",

        "question": "What aircraft are typically used on flights from Baltimore to London?",
        "answer": "British Airways is the sole carrier with nonstop service between Baltimore and London, operating Boeing 777 family aircraft on the route. No other airlines fly this route nonstop.",
        "methodology": "Aircraft types come 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",
