        "question": "What is the typical flight duration from Columbus to Washington?",
        "answer": "A nonstop flight from Columbus (CMH) to Washington (DCA or IAD) typically takes about 1 hour 20 minutes. With one stop, depending on the connecting city, total travel time often ranges from 3 to 5 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Columbus to Washington?",
        "answer": "Yes, nonstop flights run from Columbus to Washington daily. American, United, and Southwest serve the route, with American and United flying to both Reagan National and Dulles, while Southwest flies only to Reagan National. Together they offer over 200 weekly departures, with typical fares around $120–$200.",
        "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. 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. 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.

        "question": "What are the ground transportation options in Washington?",
        "answer": "At Ronald Reagan Washington National Airport (DCA), the fastest and most-used option to reach downtown Washington, D.C. is the Metrorail, with an elevated station directly connected to the terminal via pedestrian bridges; the Blue and Yellow lines provide frequent service to the city center. Taxis are readily available at the curbside of all terminals, and authorized ride-share services like Uber and Lyft offer convenient pickups coordinated through their apps. On-airport rental car counters are located in Terminal Garage 1 for those preferring to drive. While DCA is just across the Potomac River from downtown, Metrorail is the overwhelming favorite for its speed, affordability, and direct terminal access.",

        "question": "When is the cheapest time to fly from Columbus to Washington?",
        "answer": "The cheapest months to fly from Columbus to Washington are February, January, and August, with average fares as low as $182 in February. The most expensive months are June, November, and May, with average fares reaching $357 in June.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Columbus to Washington?",
        "answer": "For flights from Columbus to Washington, the best fares typically appear when booking 4 to 7 weeks ahead, with an average price around $186. The absolute lowest price of $171 is found about 45 days before departure, while last-minute bookings can spike to over $300. During summer and holiday periods, demand often pushes optimal booking windows slightly earlier, so aiming for 6 to 8 weeks out can help lock in lower fares.",
        "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.",

        "answer": "No nonstop red-eye flights operate from Columbus (CMH) to Washington (WAS), but connecting itineraries whose long leg is an overnight flight are available. Examples include a United itinerary via Chicago O'Hare with the overnight leg ORD→IAD departing at 21:40 and arriving at 00:45 (early hours), a Southwest itinerary via Chicago Midway with MDW→DCA departing at 21:00 and arriving at 23:55 (same night), and a Frontier itinerary via Atlanta with ATL→IAD departing at 21:00 and arriving at 22:52 (same night). These are based on one representative day's search and the weekly mix may vary.",

        "question": "Which airlines usually operate this route from Columbus to Washington?",
        "answer": "Nonstop flights from Columbus to Washington are operated by American, United, and Southwest. American runs the most service — up to 128 weekly flights to Reagan National (DCA), operated as American Eagle by PSA (OH), Republic (YX), and Envoy (MQ). United offers 93 weekly flights to Dulles (IAD) under the United Express brand, mostly flown by Republic (YX) with some mainline United service. Southwest flies 27 weekly nonstops to DCA. Median fares aren't available in the schedule data, but as a baseline, these carriers typically price this short-hop route competitively.",

        "answer": "As a domestic route, connections are uncommon. If needed, hubs like Charlotte, Philadelphia, or New York JFK may be used, offering broad connections and efficient transfers, though they increase total travel time."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Columbus to Washington?",
        "answer": "On-time performance is generally good, though afternoon flights face more air traffic delays. Early morning departures, particularly on American and United from CMH, tend to be more punctual."

        "question": "What documents should I bring with me to the airport when flying from Columbus to Washington?",

      },
      "q12": {
        "question": "Which airport should I use in Washington?",
        "answer": "Washington has three main airports. Reagan National is closest to downtown and ideal for business and sightseeing. Dulles offers more international and long-haul flights but is farther out. Baltimore/Washington serves as a low-cost alternative with Southwest and Spirit, though it is the most distant from central Washington."
      },
      "q13": {
        "question": "How do I get to John Glenn Intl Airport from the city center?",
        "answer": "From downtown Columbus, the most popular way to reach John Glenn International Airport is by ride‑share (Uber or Lyft) or taxi, which take about 15–20 minutes and offer door‑to‑door convenience; a taxi typically costs around $25. The cheapest option is COTA’s AirConnect bus, running every 30 minutes from the Convention Center and downtown transit terminal to the airport in about 25 minutes for $2.75, with connecting service via Line 7 and the free CBUS circulator. Driving and parking are also straightforward via I‑670 to International Gateway, with on‑airport parking garages and lots available.",
