In responce to what the USA compeditors think about the TAB card being axed, well there are not too many in Dublin. Only 3 airlines offer transatlantic services, EI to LAX,BOS,JFK,ORD (A332/3's summer and winter) And Delta to Atlanta (B777! in summer and B767 in winter), Continental to Newark (B767 in summer and B757 in winter). So no real competition.
I'm surprised EI could'nt fill a A345 or a smaller A340 on it's US routes, if Delta can fill a 777 on a daily flight to atlanta.
