Irish airline Aer Lingus will resume flights connecting Newcastle to the USA's biggest cities, and passengers can clear US Immigrations during their stopover in Dublin.
Dublin Airport benefits from US Preclearance "that allows US-bound passengers to undertake all US immigration, customs and agriculture inspections at Dublin Airport" so they can avoid lengthy immigration queues when they arrive in the USA. Passengers flying from Newcastle International Airport can connect at Dublin and clear US security there, after their one-hour flight from Tyneside to Ireland.
Aer Lingus says: "The benefit is that having cleared US Pre Clearance, passengers arriving in the US are treated as domestic arrivals, allowing them to avoid immigration queues upon arrival and pick up their bags and go."
