Five new organisations have become investors to the tune of $192 million in Skyscanner, giving it a valuation said to be in the region of $1.6 billion.
The new investment round comes from global fund manager Artemis, investment provider Baillie Gifford, Malaysian government funding house Khazanah National Berhad, online specialist Virtruvian Partners and Yahoo Japan.
The group will all take an undisclosed stake in the Edinburgh, Scotland-based company.
Skyscanner CEO Gareth Williams says the latest injection will give it the opportunity to "build fantastic further tools for travellers".
The company says it has been experiencing double-digit growth "for some years" and has been profitable since 2009.
Sequioa Capital bought into Skyscanner for an undisclosed amount in October 2013 - a deal at the time that was touted as valuing the company in the region of $800 million.
The investment firm and original backer, Scottish Equity Partners, did not participate in the latest round.
Details given to the Financial Times say that the new investment will also be used to buy out some of its existing investors' shares, but none will fully exit from the company.
Williams also says the funding will allow it to potentially pursue deals of its own, although, interestingly, it was suggested to the FT that the latest deal will in part also give Skyscanner the muscle to "fend off takeover offers from larger rivals".
Skyscanner claims to have 50 million users each month and 1,200 direct connections with partners to provide content.
