Cheap tickets are caught with a system, not found five minutes before checkout.
Book ahead: international fares often look better 2–4 months before departure.
Stay flexible on dates — midweek departures can save a meaningful share of the budget.
Compare routes and departure cities, not just one airport pair.
Cross-check the same date in two or three search tools before buying.
There is no magic weekday — a good window plus flexibility beats luck.
