The return flight is shorter, at about 9 hours and 15 minutes, due to prevailing tailwinds.", "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.", "toolsUsed": [ "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Chicago?", "answer": "From O'Hare, the CTA Blue Line 'L' train is the most-used and often fastest option to downtown Chicago, taking about 40–45 minutes for $2.50. Taxis and rideshares like Uber and Lyft are readily available with a typical 30–60 minute drive costing $40–60, while shared shuttle vans offer a middle ground at roughly $25–30 per person. Metra commuter rail also connects O'Hare to Union Station on weekdays, and rental cars are on-site for those wanting their own vehicle. Overall, the Blue Line is the go-to for avoiding traffic, while taxis and rideshares provide door-to-door convenience.", "toolsUsed": [], "references": [ { "url": "https://flychicago.com/ohare/tofrom/pages/default.aspx", "title": "Getting To and From O'Hare International Airport | Chicago O’Hare International Airport (ORD)", "favicon": "https://flychicago.com/_catalogs/masterpage/favicon.ico" }, { "url": "https://www.flychicago.com/ohare/map", "title": "Map | Chicago O’Hare International Airport (ORD)", "time_published": "2026-05-27T00:00:00Z" }, { "url": "https://en.wikipedia.org/wiki/Transportation_in_Chicago", "title": "Transportation in Chicago", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-05-15T02:56:07Z" }, { "url": "https://en.wikipedia.org/wiki/Transportation%20in%20Chicago", "title": "Transportation in Chicago", "time_published": "2026-04-13T06:59:09Z" }, { "url": "https://faa.gov/regulations_policies/orders_notices/index.cfm/go/document.information/documentID/6111", "title": "Order 3330.39 - Chicago/o'hare Airport Traffic Control Tower (ATCT) Staffing PChicago/o'hare Airport Traffic Control Tower (ATCT) Staffing Plan (Cancelled)", "time_published": "2026-04-10T00:00:00Z" } ] }, "q4": { "question": "When is the cheapest time to fly from Rome to Chicago?", "answer": "The cheapest months to fly from Rome to Chicago are September, October, and January, with average fares around $424, $433, and $439 respectively; February and August are also relatively low.

For summer and holiday periods, expect to book even earlier, as prices and demand rise sharply during those peak travel times.", "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.
