I suppose the bean counters in Lingus-Towers are offsetting any revenue gained on a direct US west coast flight against the transfer/loss of revenue on services to primairly LHR, JFK or ORD that the new service would cause due to the transfer/loss of interlining pax on those routes.
Just a spotter; this idea is all fine and well assuming no other carrier will look at this link, ie if an american company came in with a direct daily flight it would be overall a lost opportunity.
Aer Lingus need as a strategic way get after developing connectivity between Dublin and the USA to enable tranfer connections via to Dublin to/from UK and EU airports especially the airports with no direct service.
KLMs have achieved something great in terms of connectivity at AMS, no reason why EI cannot achieve this via DUB T2...
