I have been trying to find the answer to this and would like the collective wisdom of the forum to help out here.

Departing SWP-SAM-EUR-ASA-SWP.

Is this considered a xONE4 or xONE5?

The AA RTW Desk has told me (rightly or wrongly) that the xONEx as a minimun is a xONE3 which counts NAM/EUR/ASA.

I understand that starting in SWP is a xONE4, but AA RTW Desk are saying that because I am going to SAM, then it is a xONE5.

More to the point, which is which in terms of xONEx?
