I am in the process of making some changes to a Oneworld Explorer ticket and I am banging up against the maximum number of segments. The ticket originated in Cairo and at the moment it finishes in Amman. The BA Agent I am dealing with is telling me that, athough I can finish in Amman, in order for the ticket to be valid, the last segment (which I am not flying) i.e. AMM/CAI must be taken into account within the 16 segments. That doesn't sound right to me - I've never heard of that before. Does anyone else have any experience with this ?
