Methodology: learn how we calculate these charts

The charts “What's the cheapest day of the week to fly?” show the typical business-class pattern, not this route’s own: business-class bookings on any single route are too few to chart, so they are built from business-class fares Priceline customers paid across all routes over the past five years.

Each route’s fares are set to its own price level before they are combined, so the pattern isn’t skewed by expensive long-haul routes. We then scale it to the business-class round-trip fares found in recent searches on this route.

The charts “What do round-trip flights from Germany to Illinois cost?” and “When is the best time of day to fly?” are calculated directly from the business-class fares found in recent searches on this route.
