A general guide:if you really want to try, be optimist and just think. How many cities in C1w and in C3 come into play? Unlimited? Not at all. Try to write them down (create a database, excel entry, or just ascii file, whatever...). Keep in mind they are just airports serving intercontinental flights. Then, if something is cheap, it must have low BF. This is the key point. How to find it? Quite a tedious job with ITA. Perhaps expert flyer will be easier? You can sign up for a trial 5 days. Then you need to check all combinations. It will not take the whole day. It should take 10-15 minutes. Then you have candidates. Try to read fare rules and check the optimistic version (EoE permitted). It does not guarantee anything (just do not think that every EoE permitted means "dumpability") but... with those selected candidates you can continue optimistic version. It means just a strike. You may think finding strikes is impossible. Well... sometimes it is the easiest part (once you have a good candidate). And this is the end of this guide (which is silly simple and yes, has been repeated in this thread many many times). Good luck.
