I don't know what to say. I see what you're seeing - now. Back in like June when I was trying to book a flight for early September, I don't recall this calendar showing up, but it's closest facsimile was showing me no available flights if a companion cert was selected, and plenty if it wasn't. I don't disagree with the prevailing opinion involving shenanigans. I can only say that what I saw then isn't what I see now.
