The theory was 'developed' either here or in the AC forum...to do YVR-YYJ (Vancouver - Victoria, BC), about a 25 minute flight...over and over and over...then complete your RTW.
UA1K desk confirmed this is totally legal (not to me, to another interested party whom I spoke on the phone with).
We think the problem will be ticketing the thing. I mean...who in the world is gonna want to ticket that?!?!?
We know it is legal...but do you want to do that flight endlessly??! Imagine if some of your flights were cancelled...all those changes...wow!
