Turkish carriers clearly indicate this regulation on their website but unfortunately I haven't seen any non-Turkish carrier except for EasyJet mentioning this on their website. ( U2 is the only carrier that I noticed )
BA has nothing on their website about this carry-on ban and AFAIK, they do not send reminder e-mails to their passengers so it's the fault of BA and definitely not the airport authority.
I think you misunderstood my post. I meant that BA should get an aligned position with Turkish airport authorities AND then issue a comm to its PAX. It's definitely not the responsibility of Turkish AA to issue a comm. PAX transaction is with BA (cabin bag allowances form part of the terms and conditions) and not Turkish AA.
