A single search answers "what does it cost today". A watch answers "tell me when it is worth buying", which is the question people actually have.
Setting one up
- Open Settings and add a watch, or run through onboarding if this is your first.
- Origins: your home airport plus anything within a sensible drive. Add Kaunas and Riga if you are in Vilnius - the search costs the same and the ground cost is counted for you.
- Destinations: one city, several cities, or a wishlist of places you would go if the price were right.
- Date window: how far ahead to look. Airlines load schedules about eleven months out, so there is nothing useful beyond that.
- Trip length: a range of nights, not a fixed pair of dates. This is where most of the saving comes from - the same trip one day either side is routinely tens of euro cheaper.
- Target price: what would make you actually book. This is the number an alert is measured against.
How often it runs
On Free, once a week. On Pro, every night, plus an immediate deep check whenever the broad scan spots something under your target. See plans and limits.
Choosing a target price
Set it to a price you would genuinely pay, not to a fantasy. A target nobody will ever hit produces no alerts and reads as broken software. If you do not know the number, leave a watch running for a week and look at the price history first - the median is on the journey page.
A watch alerts on a real drop, not on every change. The rules are in how alerts work.
