Tuesday, Wednesday and Saturday departures tend to price lower on many leisure routes; Friday and Sunday are usually the most expensive. It's a tendency by route, not a rule — always check the date grid.
Airlines price by demand, and demand clusters on Fridays, Sundays and Monday mornings. That’s why midweek and Saturday departures often show lower fares — and why the day you buy matters far less than the day you fly.
How to use it: open the date grid or calendar view in Google Flights or Skyscanner, look at ±3 days, and let the actual prices decide. On business-heavy routes (New York–London, Frankfurt–Chicago) weekend fares can be the cheap ones; on holiday routes it flips.
Time of day matters too: early-morning and late-evening departures are often cheaper, and early flights are less likely to be delayed.
