Booking much earlier (160+ days) or waiting until the last minute (within a week) pushes prices above $300, so aim for that 4-6 week sweet spot. Summer and holiday periods tend to shift this earlier by a few weeks, so for peak travel dates consider booking 6-8 weeks ahead to lock in better fares.", "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.
