Hi no2chem,
This happened last Tuesday so it might have been before the staff were notified. Just to clarify I was on an AA domestic ticket scheduled out of T4, but with a BA GOLD (oneworld Emerald). I'm right in thinking I should have had access per oneworld rules. I really hope this has changed and staff have been notified. I don't want to walk over there again and be denied on a long layover.
