Users can type in two different cities, or airport codes, in the Google search box to bring up two boxes for entering departing and returning flight dates. Below those are links to the travel Web sites Expedia, Hotwire and Orbitz. Clicking on one of those links leads directly to flight options for their selected itinerary on that site.
"Google is testing a new search feature for specific flight inquiries between two points," Google said in an e-mailed statement.
The move comes one day after Yahoo debuted its new Trip Planner beta, which allows people to create, share and print personalised trip itineraries.
Earlier last week, Google quietly began testing a new service to enable people to post and make searchable any type of content, including used-car listings, which some speculated would put it in competition with online auctioneer eBay.
