True Blue.....you came home via LHR? You nuts? FR to BHD, then a taxi to BFS to get your car? Damn sight cheaper (and quicker) than a First Great Western from Temple Meads to Paddington, then out to LHR.
As for sustainable operations, only BFS in NI dropped double-digit % in passengers during the summer. Perhaps the demand for an operation miles from major population centres is waning. That would explain EZY dropping a rotation to BRS, and RYR adding one.
The demand for services from Derry is there. Perhaps RYR isn't the right operator to service that demand.
