As a US resident that travels on these regularly I've had my fair share of incorrect postings. Lately it only seems to be for me during IRROPS, even when I'm rebooked into F.

The first time this happened to me (back in 2008) it was a bugger trying to explain the issue but lately it has been resolved relatively quickly in an email to CS. I never use the Twitter team for anything since I don't use it.
