Google(s goog) is working on a major upgrade for its Flight Search service — in Europe at least — judging by a Sunday interview with Ryanair CEO Michael O’Leary in the Irish Independent. According to O’Leary, Google is developing a price-comparison service that will “blow comparison sites like Skyscanner out of the water” when it goes live in late March. Google Flight Search has been around since the firm bought ITA in 2011, but has failed to make much of a dent. It launched in Europe last March, but with limited functionality and missing major low-cost airlines such as Ryanair. Google said a few months ago that it was content with the overall product, but maybe it’s not — or maybe this is just catch-up time for Europe.
