Flight search site Skyscanner.net saw July-September revenue rise by 90% year-on-year to top £3.5 million.
The UK accounted for almost 10 million visitors during the quarter.

The company receives traffic from more than 200 countries with 30 of these each delivering over 50,000 visitors to the site every month.
In Europe, year-on-year traffic figures were up 47%, with Italy, Spain, France, Germany, Russia, Ireland, Holland and Poland all in the top 10 ranking countries. The US is another top 10 market, with figures up 45%.
CEO Gareth Williams said: “Creating a robust international business model has always been a fundamental element of our business strategy.
“Skyscanner’s strong international growth – in Asia and the Pacific Rim as well as Europe and the USA – is fuelled by highly profitable core markets and our expanding network of direct commercial partnerships with airlines, online travel agents and other travel companies throughout the world.
“We’re also particularly proud of the fact that growing our user base has not been at the expense of existing users – over 50% of our monthly sessions are sourced from repeat users.
“As we move forward we are keen to ensure that continues, by making sure that our development is focused on delivering a brilliant core offering first and foremost.”
