Decide what is really flexible
Before searching, split your plan into fixed and movable parts. A wedding date is fixed; a holiday week often is not. Write down the earliest departure, the latest return and the shortest and longest trip you would accept.
The narrower the real constraints, the faster you can discard options that do not fit.
Compare nearby dates and weekdays
Fares are set per flight and per fare class, so neighbouring days can differ. Many search tools show a calendar of lowest fares for a month; use it to spot cheaper days around your preferred date.
Departure day matters as much as the date: compare a Tuesday with a Friday on the same route instead of assuming one is always cheaper.
Check alternative airports
Large cities often have more than one airport, and some regions are served by airports within a reasonable train or bus ride. Compare the total cost, including the ground transfer, not only the ticket.
Weigh price against time
A cheaper flight with a long layover or an overnight connection may cost you a hotel night or a missed day. Compare total travel time, number of connections and the length of each layover next to the price.
Confirm before you pay
Prices change as seats sell. Always confirm the final fare, baggage allowance and fare conditions on the partner page before paying.
