Flexible dates and fare calendars: how to find the lowest day to fly

Why a day matters

Fares track demand for each flight. Midweek departures are often lower than Fridays and Sundays, and dates next to holidays or events can be much higher.

How to read a fare calendar

• Each cell is the lowest fare found for that departure day, not an average.
• The return date usually moves with it, so a calendar is a hint about the trip length behind it.
• A lone cheap day among expensive ones may be a quirk of one flight, so check it before you plan around it.

Flexibility that pays off

• Shift the trip by plus or minus three days.
• Compare shoulder-season weeks with peak weeks.
• Try the nearby airports on the route page.

What cached calendars cannot tell you

A calendar built from recently found fares is out of date by definition. A day may have sold out or changed price, and some entries include more connections than you would choose. Treat it as an estimate and confirm the live price.

Where to use it on SplitWing

Route and cheapest-month pages show recently found fares by month and day, and a price alert can email you when the price moves. It does not guarantee a drop.
