Despite long-held beliefs that booking far in advance or waiting for last-minute bargains will secure you the cheapest flights, the research indicated that the lowest prices on are available six to seven weeks before you jet off. The research highlights that even if prices begin to soar months before the flight, you can still bag cheaper tickets by simply keeping an eye on the costs and waiting for them to drop again. However, if you’re looking at short-haul routes, rather than domestic or long-haul, week seven may be your best chance of securing the lowest-priced flights. Travellers who have left it until the last minute to book shouldn’t despair however. You should still be able to make significant savings if you book two weeks before departure, instead of waiting until the last seven days.
