Here's the situation: I'm on a vacation - perhaps for 3 weeks - and the need arises for me to return to the point of origin for a short time - perhaps one day (a business emergency). So I buy a return ticket back to the point of origin and, upon return from that trip, resume my vacation.</font>
So that middle ticket is most likely a full fare anyways. I don't see anything wrong with that.
Like I said - if you fly all segments, then you'll most likely be fine. Just don't try and pull back to back stunts by booking thru your friendly TA, they could get in big trouble.
It's when you start combining back to back and throwaway ticket and develops a trend - then you'll raise a flag at YWG for sure.
