The original poster on Airliners.net is actually a bit late to discover that. (and always late to discover whatever that's been changed)

I posted an update on my site on 29JUL11, but I didn't bother to post it here anyways. (The poster probably "discovered" my post few days later otherwise no one bothers to check June/July 2012 schedule right now in Aug 2011)
