I hope someone with more experience can help you. I had worked part-time in a TA before and had dealt with one RTW case.

The only thing I would recommend you to do is to ask CX what are the statuses of segments 5, 6, 7, and 8, respectively. You might want to call them and ask them to view the E-TKT directly by giving them the E-TKT number of segments 5-8. Hopefully the flights you are taking are attached to those segments. In that case, The statuses should be OPEN, EXCHANGED, or CONTROL. It's normal for the statuses to be either OPEN or CONTORL. If it is EXCHANGED, AA has re-issued you new coupons for those flights, and you should get a new E-TKT from AA. You can also go to https://www.refunds.aa.com/ and enter your AA record locator with your last name to see what are the E-TKT(s) attached to your AA record locator. Don't click the refund buttom, though.
