Well I guess that answers my question that they aren't allowed to go up front. In your comment, you mention that it's designated for PY, that implies that Y pax cannot use them. I'm not sure why then AC doesn't at least just install a curtain (let alone a bulkhead) to block off PY and Y. Yes, I realize the 5 HD aircraft was never intended for AC but surely adding a curtain would improve the experience for PY?
