The most common one-stop routings connect via Toronto (YYZ) on Air Canada, Frankfurt (FRA) on Lufthansa, or Atlanta (ATL) on Delta, with a typical total journey time around 16 hours. Fares for a one-stop itinerary start around $728, with United often offering the lowest fares.", "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. Stop counts, connecting hubs, and per-airline prices are drawn from a large sample of the real fares Priceline users found on this route in the last 72 hours. We group those fares by number of stops, by the hub airport a connection routes through, and by operating airline, and report each group's share of the sample alongside its lowest and median price.", "toolsUsed": [ "route_airlines", "flight_schedule", "route_options" ] }, "q3": { "question": "What are the ground transportation options in Athens?", "answer": "Athens Airport offers several ground transportation options to the city center: the Athens Metro Line 3 and suburban railway (Proastiakos) provide direct rail access from a station adjacent to the terminal, with a base fare around €9 and trains roughly every 36 minutes on the metro. Taxis are available at exit 3 of arrivals and are the fastest door-to-door option, though more expensive. Public buses (Transport for Athens and KTEL regional services) depart from the arrivals level between exits 4 and 5, serving central Athens and nearby towns. Car rentals and private parking are also available on-site, with short-term lots at P1/P2 and long-term parking at P3.
