If you use Google Flight Search to look for an airline ticket from New York to London, you'll see the message, "Sorry, locations outside the U.S. are currently not supported."
Google is mapping plans for international flight search, but it isn't there yet.
But that hasn't stopped ITA Software, which is owned by Google and powers much of Google Flight Search, from striking a couple of new international deals.
ITA recently signed on Turkish Airlines, which agreed to a multi-year arrangement in which it will use ITA's QPX airfare shopping and pricing system for "revenue and reward redemption pricing and shopping, as well as ticket exchanges and refunds," according to a post on the ITA Software by Google blog.
The initial phase of the launch is slated to take place in the third quarter of 2012, ITA says, and eventually Turkish Airlines customers would be able to use the tools on TurkishAirlines.com, THY mobile apps, travel agencies and in ticket offices.
Meanwhile, in Japan, H.I.S., described as "one of the largest Asia-Pacific multinational travel agencies," last month began using QPX on its consumer website.
Of course, Turkish Airlines and H.I.S. aren't necessarily receiving the same ITA flight-search technology that Google Flight Search uses, and that will become more of an issue for ITA customers as Google Flight Search evolves.
