Reasons to use ONE fares?
OK I am a newbie to these fares. I can understand a nice vacation or if you happen to have a biz meeting in asia then europe then back to the US. as a MR does it make sense? (transoceanic RT is $500 and 10K miles so better miles value).
Also if you fly JFK-NRT (for example) in F it is probably cheaper just to go around the world am I correct?
Anyways what are the other tricks of the trade?
