I booked my LONE4 by calling AA a few months ago. I've had quite a few schedule changes & technical issues, however, I've been able to see everything online since the beginning.

About a week ago (or maybe a bit more) it became impossible to log-in to my reservation online. Using the link in my email or manually logging in made no difference.
I'm getting the following error:
Notice
We are experiencing technical difficulties and are unable to display your reservation at this time.
Please try again

It's quite annoying because I still have to change some dates once the trip starts. And I don't really trust the system anymore because of the schedule changes (cancelled leg, without letting me know).

Yesterday I called the RTW desk. They saw nothing wrong, besides another schedule change. So she reticketed it again (now in the mail I got my last leg is missing). However, still impossible to check my reservation online.
Just called the AA web service, but they also couldn't help me and told me that a res with more than 8 segments is unlikely to show up online (which is ........ of course).

I found 1 workaround: the app is showing my full itinerary.

But are there any other ways to solve this, or people with similar experiences?
I'm guessing all the schedule changes messed it up.

Call AA and have them "clean up" the PNR. Sometimes after numerous changes they don't work on the website. It is not reissuing or reticketing.

Thanks!

What exactly does 'clean up the PNR' mean? Just so I know what to answer if the AA representative doesn't know what I'm talking about.
Can the regular customer service reps do this, or even the RTW desk? Or only the IT dep?

It cleans it up. Not sure exactly what it does, but it can help fix broken PNRs. I had to do it for paid and award tickets that had numerous changes, both from my actions and AA's. Any regular customer service reps should be able to do it, but might balk when they see it is a RTW. RTW desk might have shorter wait times due to the weather issues though.

Starting to hate this ticket more and more.
So I called the RTW desk again, with my problem, and she didn't feel like looking into it, but said my PNR was fine. She transferred me to web. There they said they couldn't do anything because it was something international (also said the PNR was fine), so they transferred me to the international res department (or something like that). The rep put me on hold for 25 minutes, while talking to a supervisor, but then my connection dropped.
So I called again, another girl contacted her supervisor again and after 15 minutes she told me the website is having technical difficulties, and the problem should be solved somewhere in the future...
Like she needed to be talking to her supervisor for 15 minutes (and the other one for 25) only to come up with that explanation... They just don't know what's wrong.

For a 9000 USD ticket (2x4.500), you'd at least expect them to get things working the way it's supposed to work...
