Star Alliance Round World Upgrades

[sudsoz]

In a few weeks I am doing a Star Alliance Round World going from MEL to MIA then FRA and then back through Asia. Booked in economy I tried today to use miles (held with SQ) to upgrade parts of it.

I was told by SQ today that both UA and NZ will only upgrade from Y or B class fares and my agent says that the only economy class for the Star Alliance Round World is M class.

The lady at UA agreed with my assessment that the Star Alliance Round World is therefore not upgradeable. I have asked SQ the question and not got an answer yet.

Any one have any intel on this? Is there another way?

It is upgradeable using the miles/upgrade instruments of each airline you fly.
Eg if you have enough airpoints dollars then you can upgrade the NZ flights (subject to availability of course).

Kiwi is right - it is entirely dependent on which instrument from which FFP you're using.
