All the heavies pulling out?
See earlier posts- it looks like Aer Lingus (3 cities daily), Continental, Delta, US Air and Canadian charters at least will be operating at Shannon for the foreseeable future. I don't understand the desire of any poster- particularly those living anywhere within a reasonable drive from Shannon, to see fewer transatlantic services from a west of Ireland airport.
By the sound of Shannon's U.S. Customs & Border Protection (CBP) plans, passengers there will enjoy a significant improvement to their air travel experience. It may even encourage some travellers to use Shannon as their transatlantic gateway rather than Dublin, given the convenience and time-saving benefits offered by full CBP.
