Everything added and modified has added tonwhat today is very dated and klugey software. When AA told us eVip (SWU) we’re going to be shown in our accounts, it took something like 18 months to accomplish! (It turned out to be a good thing, as our eVip validity was extended from one year to the current “remainder of this status year plus the following one”.)
Prior to bankruptcy, AA had an MOU with Hewlett Packard to design an entirely new system called Jetstream. That was cancelled and the parties settled on an agreement in 2012. After the takeover, Doug Parker selected Sabre as the PSS (over available systems like Amadeus, etc.)
Short of it: AA, and of course we, are stuck with an antique. First out doesn’t mean the best or most capable after other competing systems are built. It kind of stinks, but that’s where we are. (I’ve been flying AA, through the good and the bad, since the 1940s. I’ve seen much of this occur.) Think Slow Loris.

Thanks for the lesson. Sure is interesting. Of course, I now realize that I could be better prepared before calling in. I also understand that there is no alternative to calling if the online account doesn't show an option to change the trip. The question was pretty much along the lines of ... maybe it is hidden under some sub-menu or remote section of the website that experienced users know of.
By the way, my username has nothing to do with the name Loris (I am male) - I never realized that it would read this way. Long story about how I had a hard time creating an ID on some website ages ago (everything logical being taken) and so I patched some arbitrary name together. The name refers to the Slender Loris (a strange creature - look at an image if you are unfamiliar). Neither am I slender...
