        "question": "Are there any direct flights from Baltimore to Chicago?",
        "answer": "Yes, there are plenty of nonstop flights from Baltimore (BWI) to Chicago. Southwest, American, United, and Frontier all fly the route daily, with Southwest alone offering about 160 weekly flights to Midway and another 31 to O'Hare. In total there are roughly 338 nonstop flights a week across both Chicago airports, with departures from early morning through late evening — including overnight red‑eyes on Southwest and Frontier.",
        "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. 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": "What are the ground transportation options in Chicago?",
        "answer": "From Chicago Midway, the CTA Orange Line train is the most popular and fastest way downtown, taking about 25 minutes. Taxis and rideshares like Uber and Lyft are readily available, with cabs using a metered fare. Rental cars and shared-ride vans are also options. The Orange Line station is right at the airport, making mass transit the most-used choice.",

        "question": "When is the cheapest time to fly from Baltimore to Chicago?",

Overall, the cheapest months are January, February, and September, with averages between $231 and $238, while the most expensive period is late March at $291 on average.",
        "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 Chicago?",
        "answer": "For flights from Baltimore to Chicago, the best fares are typically found when booking about 5 to 8 weeks ahead of departure, with the absolute cheapest single-day price around 45 days out at $169. Booking further out than that (e.g. 180 days) can cost significantly more, around $259, while last-minute bookings are also pricier. During summer and holiday periods, demand pushes prices up, so you'll generally want to book toward the earlier end of that window or even a bit sooner to lock in a reasonable fare.",
        "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.",
