I've had luck booking many segments like this but an agent just told me a memo was sent out limiting the number of segments on Asian tickets although she would not say to how many which I found strange and annoying even after I asked. I was booking a five segment European one way which she didn't want to do but she came back and said it is allowed since they haven't changed the rules yet. Anyone know the details of the new memo?

Edited to add she was a global services agent although she could also be making stuff up regarding the segments.
