With one stop, common layovers include Charlotte or Atlanta, and total travel time typically ranges from 4 to 6 hours. Return flights are similar in duration." }, "q1": { "question": "Are there any direct flights from Chicago to Charleston?", "answer": "Yes, there are plenty of nonstop flights from Chicago to Charleston every day. American, United, and Southwest all fly the route daily — American and United out of O'Hare, Southwest out of Midway — with over 160 weekly departures combined. Southwest also runs a few late-night red-eyes from Midway on select evenings.", "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 and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares 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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database.

The most expensive months are April, March, and June, where average prices reach $452, $435, and $405.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": [ "seasonal_prices" ] }, "q5": { "question": "How far in advance should I book tickets from Chicago to Charleston?", "answer": "For the Chicago to Charleston route, the optimal booking window is 3 to 6 weeks before departure, with average fares around $276. The sweet spot is about 30 days out at $267, while last-minute bookings can spike to $467. For summer and holiday periods, you should extend that window by a few weeks to avoid higher prices.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": [ "booking_timing" ] }, "q6": { "question": "Are overnight (red‑eye) flights available from Chicago to Charleston?", "answer": "Yes, overnight red-eye flights are available from Chicago (Midway) to Charleston on Southwest Airlines, operating Monday, Thursday, Friday, and Sunday with departures around 9:00–9:50 PM.
