According to new global travel statistics from momondo, Brits can save money by booking flights at least 53 days in advance of their departure.
By analysing 7.5 billion airfares worldwide, the site found by booking travel early - less than two months in advance of departure - consumers could save an average of 29% on flight costs.
Conversely, the most expensive tickets are to be found, if travellers chose to book their trip on average three days before departure. The company also found that flight price can also vary hugely, depending on the day of the week, with the cheapest departure fares typically found on a Tuesday and the most expensive on a Saturday.
According to the travel site, time of the day is also important to consider when booking, with evening flights (between 18:00 and midnight) typically the cheapest time.
Lasse Skole Hansen, the company spokesperson, said: "We would always advise travellers to remember these golden rules, to bag the cheapest ticket. In general, it pays to book flights two months in advance. We found these trends consistent across the board, so bargain hunters should consider flying at night and on a Tuesday, if they want to save money on their travels."
