The distance between Chicago (measured from Midway) and Shanghai is about 7,065 miles.", "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.", "toolsUsed": [ "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Shanghai?", "answer": "Shanghai Hongqiao Airport (SHA) is directly integrated into the Hongqiao transportation hub, so ground connections to the city center are excellent. The fastest and most-used option is the Shanghai Metro, with Lines 2, 10, and 17 serving the hub; Line 2 connects directly to the old city center, Lujiazui, and even Pudong Airport. Taxis and local buses are also available right at the airport, and the adjacent high-speed rail station offers intercity connections.

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.

The single cheapest day to book is 30 days out at $336, while booking very early (e.g. 180 days ahead) tends to cost significantly more at $507. For summer and major holiday periods, demand is higher, so you'll likely want to lean toward the earlier end of that window or even slightly before it.", "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.
