Direct answer
Should I book this flight now or wait?
Book now when the current fare fits your budget, the trip dates are fixed, and the cost of a price rise matters more than the possible saving. Wait only when your dates or airports are flexible and you can tolerate the fare moving against you. A route-specific price range is more useful than universal “Tuesday” advice.
The answer changes if…
- Holiday, school-break, event, or limited-service dates reduce replacement options.
- Nearby airports or flexible departure days create meaningful alternatives.
- The tool has observed route fares versus only a seasonal model estimate.
