Blue Islands were conducting a servey into what routes they should look into next just before Christmas. Unless they are taking their time, then it might be along time until we see a LBA route!
They said that a Northern route may not be viable. MAN will serve JER twice daily and Gernsey daily from this spring, so maybe a route from LBA would have too much competition from MAN - as JER pax can make a business trip within a day to MAN.
