On the subject of Delta, I think they have added Boston to the list of destinations served from LGW, however, it is a connection service, as it forms part of the service to New York JFK (LGW-BOS-JFK).
Still doesnt make up for a poor livery design though…:D
Not usual to have to quote yourself…but I enquired at the Delta ticket desk to see if they had added BOS as a destination from Gatwick, and the kind lady said it was just a one-off…
