FlyerTalk is an interactive community that provides up-to-date information on travel-related loyalty reward programs.  Here is an example of how I use it with the Miles and More Program from Lufthansa. Last year Lufthansa had a few promotions that were not advertised.  The promotion provided a bonus of 5,000 miles each time I flew from the Middle East to Europe in business class.  So I was able to rack up an additonal 25,000 miles.  On top of that Lufthansa had another unadvertised bonus which gave 10,000 miles if you flew 38,000 miles within a 3 month period.  So I made 35,000 extra miles by spending about 10 minutes registering for these programs.
