Best time to book flights for the cheapest fares

The best booking window

There's no single magic day, but fares are usually lowest when you book in the right window: about 3–8 weeks before a domestic trip and 2–5 months before international travel. Prices tend to rise sharply in the last two weeks.

Best days and times

• Depart mid-week (Tue/Wed) rather than Friday–Sunday.
• Early-morning and late-night flights are often cheaper.
• Avoid public holidays and school breaks where possible.

Be flexible to save more

If your dates can move, compare a few days either side — shifting one day often drops the fare noticeably. Search your route on FlyLemo and try nearby dates.
