To combat the bias toward U.S. airlines and court American travelers, carriers who fly under foreign flags tend to offer not only the best service but also the best deals. Consider this: Singapore Air offers a round-trip flight from New York to Frankfurt for $397, including all taxes and fees, roughly $200 cheaper than what you'd pay in the summer. The offer is good through Sept. 13, and you must travel between Nov. 1 and Dec. 16. The best nonstop deal from an American-based carrier? According to Orbitz, Continental has a nonstop for $433, followed by Delta at $491.
Flying foreign means lower prices and better service, and because of the bias, it could result in a better seat too. "One thing to keep in mind when you're dealing with foreign carriers that fly to Europe, there's a good chance you'll find more seats available on the flights because the U.S. carriers always sell out first," said Geoff Silvers, director of merchandizing for Orbitz.
