If you haven't Googled a flight itinerary recently, you should try it.
Google's Flight Search, the fledgling search engine that lets you find a ticket and book it directly through an airline, is getting better. Much better.
In recent weeks, the new service has quietly expanded the number of U.S. cities it covers. (It won't say how many destinations are being served, except that the number has doubled.) Google has also integrated flight searches into its authoritative search results, making them easier to find and use.
