Shannon Airport is the third-busiest airport in Ireland (after Dublin and Cork), currently seeing almost two million passengers a year. Flights to Shannon Airport arrive from across the UK, as well as from a few key hubs elsewhere in Europe and the US. The five busiest routes include those to the three London airports ( Heathrow, Gatwick, and Stansted), as well as Newark and JFK in the US.
Shannon Airport was the first airport in the world to offer full US pre-clearance outside of the Americas. However, changes to flights offered in recent years has seen a dramatic (almost 40 per cent) drop in annual passengers. The airport has few facilities and is not as busy as it used to be, but staff members are friendly and your experience of this efficient little airport should be a good one.
