United Airlines is a member of the Star Alliance group of airlines. As such, their frequent flyer programs work interoperably and systemwide. What this means is miles earned on flights operated by any of the member airlines can be used to book award tickets for flights operated by other airlines within the Star Alliance airline network. You can fly with Lufthansa, Austrian, Swiss, Thai Airways, Singapore Airlines and other Star Alliance operators. Google "star alliance" for a list of these airlines.
