Why don't you give Amex a call and request that they report your 30 year old account to all 3 CRAs? Explain that it's only on one of your credit reports.
An AoOA of 30 years vs 2 years is significant and could make a huge difference in how Chase views you as a potential customer.
Cool, definitely report back and let me know how it goes. I had Amex do an off-cycle reporting for me a month or two back and it took all of 1 minute through chat. For some reason my account didn't report to all 3 bureaus one cycle, so I requested a re-reporting and within a week or so it was reported correctly across all 3 bureaus.
