Thanks for the thoughts so far.
I am now looking at a RTW ex-Turkey (either Istanbul or Ankara) in business. I have found what seems to be an ok agent to ticket it, or can even do it in Canada when I am there soon.
However, I am struggling with routings..unfortunately I am on a Mac so the Star tool wont work, otherwise I would play with that.
Much as I hate to ask this, does anyone have any fairly simple but interesting routings to take me from IST through Asia to MEL (prob about a week or so on this, so more flying than stopping!). I will then want to come back prob to LAX, YVR - across to NYC and LHR then IST (if this is allowed). No real time constraints on way back.
Have only flown AC in business and UA in domestic F, so would be nice to try out lots of other airlines
Any help appreciated, and sorry for asking such an open ended question!
