Wish that were the case Rally, but insiders at DL have pointed to overall disappointment with the loads on the SNN-ATL. Of the "new routes" (i.e since they de-linked it from the DUB service) it has been one of the disappointments.
The 764 was scheduled on the route, possibly in expection of higher loadings. It has harder to switch aircraft to match capacity to demand mid way through a flying season than you would think!
Hopefully next year brings better things for the service! One would assume it is back to a single shared DUB-SNN-ATL for the winter?
