When short-haul fares actually move

This is written to be used rather than admired. Each section below is a decision about airline pricing, and each one has a default.

There is no magic day

The persistent belief that fares drop on a particular weekday reflects old distribution practices rather than current pricing. Modern revenue management adjusts continuously in response to bookings on that specific flight. Two flights on the same route the same day can move in opposite directions for unrelated reasons.

The trend is upward on leisure routes

Low-cost carriers typically release seats in fare buckets that fill progressively, so later booking usually costs more. Last-minute bargains are far more common on package holidays than on short-haul point-to-point flights. Waiting for a drop on a popular weekend route is generally a losing strategy.

Flexibility beats timing

Shifting a departure by a day, or using a different airport, moves fares far more than choosing when to click buy. Search tools that show a whole month at once make this visible immediately.

Being flexible about the destination as well produces the largest savings of all.

Watch the extras

Headline fares on low-cost carriers exclude bags, seat selection and sometimes check-in at the airport. A cheaper fare with a bag added is frequently more expensive than a higher fare including one. Comparing the total for what you will actually take is the only meaningful comparison.

If that does not fit your week, it is not a failure of willpower.

Set alerts and then stop looking

Price alerts on a route do the monitoring without the daily checking that produces anxious decisions. Deciding in advance what price you would accept converts the purchase into a rule rather than a judgement. Repeated searching does not raise prices, whatever the folklore says, but it does raise stress.

The takeaway

Be flexible about dates and airports. That moves fares far more than when you book.

Pick the one that costs you least, and let the rest wait.
