Today is the cheapest time to book your August bank holiday flights

We've crunched two years of data to reveal when to find the lowest fares

If you’re planning a bank holiday escape, the cheapest time to book your flight is around two months and three weeks in advance, according to Which? Travel research.

By analysing two years of flight-booking data from Skyscanner, researchers have predicted that this week – and today in particular, June 3 – is best to bag a bargain on a late August airfare.

Flight prices fluctuate with demand, meaning it’s impossible to give a definitive answer on how far in advance you should book to always get the lowest price.

However, by crunching 2017 and 2018 data for thousands of return economy flights worldwide, we were able to find the booking sweet spots for popular holiday periods.

Hurry deals, early-bird deals and discount vouchers: Which? Travel is always investigating how to get the best price on your holiday. Find out more about Which? Travel

Bag a bank holiday bargain

Which? looked at the cost of flights from the UK to a variety of worldwide destinations to help sun-seekers find a bank holiday bargain. It’s not an exact science, as the best time to book does alter year on year, but the cheapest periods were roughly the same.

If you book almost three months before the long weekend, flights should be 8% cheaper on average than at any other time.

Although we’ve pinpointed 3 June as the best day, you may secure a late August deal for a week or two afterwards, too.

Our data found that while Sundays are typically the most expensive day to travel, they are the cheapest day to book (Wednesdays are priciest). But, how far in advance you book is more important than the day of the week when it comes to finding the best fare.
