Where does SNN-LGW appear in Cara Magazine? I've had a look at the Oct/Nov issue and can't find it, the separate route map for SNN and the other smaller bases doesn't show any route between SNN and LGW and neither appears in the list of routes below the map.
There are only four lines from the LGW base, those four cover the current routes although one does go over LHR and doesn't seem to reconnect to any other route but you have to assume that's the DUB route.
