Overall flight prices have fallen by at least 10% in the past year with long-haul fares leading the way.
Vancouver has seen the greatest drop, with an 18% decline in prices year-on-year to an average of £576.28, which could save a family of four more than £500, according to analysis by travel search engine Skyscanner.
Flights to Boston and Hong Kong have seen prices reduce by 13% and 14% to £477.34 and £519.83 respectively.
Most recent data has seen prices fall by 10% across all flights to all destination, with a 6% decline across flights outside of Europe and 7.5% for domestic flights.
But in order to secure the best deals, consumers have to book months in advance – 29 weeks ahead in the case of Vancouver and 30 weeks for Toronto.
Skyscanner travel editor, Cat McGloin, said: “We have seen an average 10% drop in flight prices over the last year, but what we are now able to see is where the biggest drops are for those long-haul destinations and show travellers that those far flung locations might be more affordable than they think.
“Finding cheap prices can be easily if travellers are flexible, choosing to depart from a different airport or changing the date of travel are just two quick hacks to consider.”
