Trip planning site Kayak launched a new Travel Trends portal revealing the most cost-efficient periods to travel based on data from annual searches.

The site reveals historic and predicted costs from January 2014–December 2018, for flights to and from specific destinations, as well as fluctuations in hotel and car rental prices. It lets travelers monitor pricing year-by-year and month-by-month, spot the most popular destinations, view search patterns for cities over time and identify cities trending and declining in popularity.

“We’ve always had great tools to help travelers plan and manage their travels and now, a market first, Brits can use our Travel Trend Dashboard to help get a comprehensive overview of the ever-changing face of travel,” said Suzanne Perry, travel expert, Kayak. “At Kayak we want to share our travel know-how and provide profound insight into travel trends. There is a lot of interest in this kind of data, and it is exciting that through this dashboard this information is now available for everybody.”

If a traveler is flexible in terms of travel dates, passengers will be made aware of peak seasons for travel, providing evidence for shifts in price and popularity throughout the year. The data is pulled from the 1.5 billion searches the website and app generate annually and is updated monthly to provide the most relevant information.
