Nonstop flights typically take 1 hour 34 minutes, while the return leg is longer at 1 hour 54 minutes due to prevailing winds.", "methodology": "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).

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.

Summer and holiday periods tend to require booking on the earlier end of that window or even further out, as demand drives prices up.", "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.
