Methodology: learn how we calculate these figures

The best day to fly and how far ahead to book shown in this table are built from the prices Priceline customers actually paid for flights to this destination over the past 12 months or more.

Where a route has too few bookings to fill a figure, we borrow the shape from a group of routes with similar price behavior and fit it to the fares booked on that route.

Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches.

The cheapest round-trip and one-way fares, the good-deal price and the best time of day to fly come directly from the fares found in recent searches, not from historical bookings.
