Finding cheap flights has less to do with magic dates and more with a repeatable process. This guide walks through the tactics that actually move prices: when to book, how to search, which airports to include and why the 'Tuesday trick' is mostly a myth.
Start with a realistic budget
Decide the most you'll pay for the round trip before you open a single search tab. When a fare dips under that number, you book it — indecision costs more money than any timing trick saves.
Use flexible search across dates and airports
- Search whole months, not fixed dates — the fare calendar shows cheap days at a glance
- Include nearby airports; an extra hour of train ride often halves the fare
- Compare one-way and round-trip prices separately, then combine the cheaper pair
- Use the 'explore everywhere' map when the destination itself is flexible

When to book
The old rule-of-thumb holds up broadly: book international trips two to six months out, shorter-haul flights one to three months out, and avoid the 14-day window where prices climb. Booking earlier than six months rarely helps — airlines price high at launch.
- International: book 2-6 months ahead for the sweet spot
- Short-haul: 1-3 months ahead
- Peak travel windows (summer, Christmas): shave time against the calendar and book earliest
- Flexible-dates alerts will out-perform constant checking
Set alerts instead of checking sites
Price tracking alerts do the surveillance work you'd otherwise do manually. Enter a route, set a target price, and you'll get notified when a fare dips — this is how routine savings of 10-30% happen, because most cheap windows last only hours.
What works and what doesn't
| Tactic | Verdict |
|---|---|
| Booking on 'the cheapest day of the week' | Myth — day-of-week savings are tiny and inconsistent |
| Clearing your browser cookies | Myth — prices have never been tied to cookies |
| Flexible date searches | Wins — weekdays and shoulder dates regularly cost less |
| Nearby airports | Wins — secondary airports often cut fares dramatically |
| Setting price alerts | Wins — automation beats manual checking |
| Travel in shoulder season | Wins — the cheapest month is usually the off-peak one |
