Well said EI-BUD. Aer Lingus will have a profitable SFO service if they continue to develop DUB as a transatlantic hub offering connecting flights between their European and US destinations.
You know I remember clearly this was the plan when the Fokker 50 was introduced to support the SF340s and we're twenty years down the line and the long haul network isn't a whole lot bigger.
OK more aircraft but it's still a core Chicago, Boston and New York point to point with Florida holidays having come into the picture.
I think they manage to get come degree of connectivity on price to fill the aircraft that the local market supports but I think it's fair to say, the guys up front paying top dollar haven't been enticed in sufficient numbers.
You can't build a hub beyond your local market without that sort of cross subsidy alas.
