No problem accessing FT from the AC at ORD (between H and K) yesterday evening, or DFW (at C19) on Thursday. I've also always been able to access my company's e-mail site by typing its URL.
However, when I try to open an FT thread in a new window so as not to lose the index to a forum, none of the AC computers will allow it. I have to go to the thread, then return to the index.
