Previously, Microsoft had acquired Farecast in 2008, a website in the computer reservations system industry that offered predictions regarding the best time to purchase airline tickets. Farecast was founded in 2003 and collected over 175 billion airfare observations by 2007. Farecast's team of data miners used these airfare observations to build algorithms to predict future airfare price movements. Microsoft integrated it as part of its Live Search group of tools in May 2008 as Live Search Farecast; Microsoft rebranded it as Bing Travel on June 3, 2009, as part of its efforts to create a new search identity. In 2009, there were allegations that Bing Travel had copied its layouts from Kayak. com; Microsoft denied the allegations. By January 2013, Bing Travel results were powered by Kayak. com. As of January 2014, the fare prediction feature had been removed. As of May 2015, Microsoft rebranded the service to MSN Travel. In August 2015, MSN Travel flight search pages changed from being powered by Kayak. com to its competitor Skyscanner.
