I'm willing to bet you can go back farther for a "fee". Banks are all about fees.
I called them, in fact I was on hold when I made the OP. I complained to the CSR that I couldn't see more than 120 days activity whatever I clicked. She tells me I received an email around the beginning of the year with a link to the last year's activity. She asked me to look for that email. I said "hold on, I'm looking," I have a big inbox. I find the email searching on "chase." I hit the link and eventually have the PDF open and I save a copy to my machine. I ask her why on earth they don't have a way to find it at the site instead of having to mine my email data. No answer there, but I have what I need and thank her, print it out and it was absolutely great to have that document when doing my taxes yesterday. Everything's organized into type of transaction, so all the grocery stuff was together, all the medical/dental together, entertainment together, etc.
