The truth about cheap fares
Airline pricing moves with demand, not with your browsing history. The old trick of clearing cookies rarely changes a price; what changes it is when you fly, from where, and how far ahead. Fares are lowest when demand is soft, so the real strategy is to travel when others will not. Booking windows and route data are published by the airlines themselves and summarised in consumer guides such as Elliott Advocacy.
Pair the fare with our daily cost tables so the cheap flight does not hide an expensive city.
Timing: the booking window
For short flights within Europe, the cheapest fares usually appear six to ten weeks before departure. Book too early and you pay full-price fares before sales; book too late and you pay last-minute premiums. For long haul, four to six months is a reasonable window. Set a price alert and buy when the fare dips rather than waiting for a perfect low that may never come.

Routes and airports: where the savings hide
The biggest single saving is often a route change. Flying from a secondary airport, or accepting one stop instead of a direct flight, can cut the price sharply. Compare a nearby city's airport too; a short train ride to a cheaper departure point sometimes pays. Check the baggage fee before you compare, because a low headline fare with a paid bag is not cheap.

There is no perfect day to book, only a range of weeks where the fare stays low.
Tools and how to use them
Use a metasearch site to scan dates, then book direct with the airline so changes and refunds are simpler. Price calendars show the flexible days at a glance, and for a whole trip the trick is to shift the date by a day rather than the airline. If you are budget-focused, our weekend budget guide shows the same method on a real example.
Myths worth ignoring
Clearing cookies does not lower fares. Fare deals do not always arrive on a set weekday. Hidden-city ticketing can void a return and is not worth the risk. Skiplagging aside, the honest levers are date, route, airport and baggage, and none of them require tricks. Ignore the gimmicks and the strategy becomes simple.

A repeatable routine
Watch a short list of routes, travel Tuesday to Thursday, book six to ten weeks out, and book direct with one bag included. That routine beats any single hack, and it works in every year. Do it for three trips a year and the savings add up to a whole extra trip. For the accommodation side, see our hotel loyalty guide.
