I understand from previous posts that on ST RTW i is not possible to upgrade.
Is it possible to skip a section? What I mean is, I might fancy using some miles to take advantage of a promo for a particular section (assuming I already have bough my RTW icket). I accept that I would be paying twice for that section.
I have done this before on the return leg of a journey, and they seemed quite happy with it. I believe I could not do it (officially) on the outward leg of a cheap economy journey, as this would invalidate the return leg (or something like that). My memory may be faulty, but I think I managed this once, and it comes back to 'it depends who you talk with'. Anyway, that's an aside really.
Thanks for any help.
