We are a family of 5 traveling on 5 separate record locators [DONE4]

I can pull up 4 of the records on aa.com, I cannot pull up one of them. I called AA RTW and they said all is fine. However, usually when I cannot pull up a reservation this means I will have problems at the airports.

The last change we did and paid was the last segment [CX change from HKG-ICN to HKG-PUS]. We also had Y to D upgrade that cleared on that flight [AA RTW UK did this]. AA is able to e-mail me the itn and everything looks fine [right places, all business class, etc.]

Any ideas on what might be going on?
