Until now, it has been U.S. only - meaning only flights within the U.S. While the starting point still needs to be U.S., it is now including international flights. "Starting today, you can find flights, including international destinations, from the U.S. quickly and conveniently," says product manager Eric Zimmerman in a post on Google's Inside Search blog.
"A quick click over each city on the map will show the different options available to you almost instantly -- and click the chart next to the dates to show alternative dates so you can make the best choice for your trip," says Zimmerman. "Likewise, if you’re looking to hop over to Europe for a weekend from New York City and are flexible with your departure and arrival airports, you can see the options for your gateway."
Earlier this month, Google announced it started powering an air travel reservation service for Cape Air. Competitors are surely not thrilled. As you may know, the FairSearch Coalition, which is comprised of Google competitors (mainly travel sites, but including Microsoft) was formed to see the company's acquisition of ITA Software blocked entirely. Obviously that didn't happen.
Google said it has now included over 500 airports outside the U.S. in Flight Search, and is working to expand it more in the near future.
