Skyscanner has reported turnover is up by 96% at £65.8m, the fastest growth in three years.
The Scottish-based travel search firm said users of its website and app have doubled to 25 million each month at its results ending December 2013.
It has already announced plans to recruit 200 more people during 2014.
The company began in 2003, focusing on flights but during the past year, it has moved into hotel and car hire searches, buying a Barcelona technology firm, Fogg, to help develop the software.
Last October, it received investment from Sequoia Capital, a leading US technology investment firm, which valued Skyscanner at $800m (£490m).
It has expanded beyond Europe, with offices in Singapore and Beijing. Its Asian traffic grew last year from 4% of traffic to 20%. The company has also opened an office in Miami, to grow its business in North and South America.
It has announced plans to create another 200 jobs during 2014, with a focus on software engineering,
Shane Corstorphine, the chief financial officer, said: "Our growth has been predominantly driven by our flight search on both web and mobile platforms, reinforcing our position as Europe’s leading flight search site, while seeing rapid growth in the Americas and particular in Asia-Pacific.
"With an increasing number of consumers booking their travel on the go, mobile will remain a key part of our strategy over the next 12 months and beyond".
Gareth Williams, who co-founded the firm, said this year will see a focus on growing the hotel and car hire parts of the search engine beyond roughly 10% they now represent.
