All except Allegiant operate daily, with frequent departures throughout the day; Allegiant runs only on Mondays and Fridays with a single morning departure. The flight takes about 2 hours and 35 minutes on average, and United is the most reliable with an on‑time arrival rate of roughly 77%.", "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.", "toolsUsed": [ "route_airlines", "flight_schedule", "redeye_flights" ] }, "q3": { "question": "What are the ground transportation options in Cincinnati?", "answer": "At CVG, taxis and ride-shares like Uber and Lyft are the fastest and most-used options to reach downtown Cincinnati, taking about 20 minutes and costing roughly $30–$40. Public transit is available via TANK bus Route 2X Airporter, which runs to the city center for $2.00, though it's less frequent and slower.

Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve.

The absolute lowest price appears around 35 days before departure at $179, while booking very early (over 5 months out) can be significantly more expensive. Summer and holiday periods tend to push optimal booking slightly earlier, as demand raises prices closer to departure.", "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.
