I'm sure there's a thread (or 20) for it but dang if I can find it. Booked D1 ATL-DUB with return BCN-ATL. BCN-ATL is an A330-300 and the seat map isn't herring bone but just 2 parallel seats (traditional configuration) in the middle. The pictures I see online show DL's A330 D1 as herring bone. Are they herring or has there been a change? Thanks in advance and sorry for what I'm sure is a duplicate question.
