It's been quite a month for Dohop, with the Icelandic metasearch provider this week securing a deal to power flights on Russia's biggest search engine.
Yandex currently commands around 60% of all search engine traffic and is the only country in Europe where Google does not have a dominant position.
The engine's flight search product will display content directly from Dohop, alongside its own content from advertising partners.
The Yandex agreement comes fresh on the back of working with London's Gatwick Airport on an interesting deal to let passengers connect flights between low cost and legacy carriers in a single booking.
Dohop's Self-Connect tool will also be available on the Yandex platform.
CEO David Gunnarsson says the deal the agreement with Yandex "is a big step forward for Dohop".
"It validates the hard work and innovation we have put into our flight search technology and lets us help an emerging market find and book flights."
Yandex was one of the first major search engines, in November 2012, to place flight search tools at the heart of the existing organic search results, using content from the likes of Amargo and OneTwoTrip.
