If you are planning a flight from the US to Ireland, you will most likely arrive at one of the three major international airports in the Republic of Ireland: Dublin Airport (DUB), which services the eastern counties, Cork Airport (ORK), servicing the southern counties, and Shannon Airport (SNN), serving the western counties.
Although Dublin Airport and Cork Airport rank ahead in terms of passenger traffic, Shannon Airport is the most centrally located of the three and, therefore, it allows for greater access to the interior and western counties. It is also an excellent staging point for exploring the Aran Islands off the coast of County Galway.
Flying into Dublin Airport puts you in the nation’s capital and allows for exploration of County Wicklow, County Kildare and County Meath, whereas Cork Airport provides excellent access to County Cork, County Kerry and County Limerick.
The Heartland of Ireland, which includes the counties of Roscommon, Tullamore, Mullingar and Offaly, lies midway between Dublin Airport to the east and Shannon Airport to the west, so a flight into either one should provide ready access. However, you are more likely to get better public transportation out of the capital city of Dublin.
If you’re looking for inexpensive, nonstop flights to Dublin, Ireland, why not consider flying aboard Norwegian Air International from New York Stewart Airport (SWF)? Located about an hour outside of Manhattan in Orange County, it’s a good alternative to the hustle and bustle of Newark Liberty Airport (EWF) and JFK Airport in addition to being only a short train ride away.
Travelers with limited mobility can take advantage of a variety of specialized services at the New York Stewart Airport (SWF) when flying to Ireland. Parking facilities at this airport feature areas designated specifically for vehicles with disabled occupants.
As travelers wait for their flights from the United States to Ireland, airport lounges are generally regarded as one of the best locations to unwind. Most economy passengers using Salt Lake City International Airport (SLC) to fly from the US to Ireland opt to relax in the Delta Sky Club before they take off.
Travelers who plan to go on vacation in Ireland from the US with their kids should consider flying aboard Norwegian Air International from New York Stewart Airport (SWF). This airline serves direct flights from SWF Airport to Dublin Airport (DUB). Use of direct airlines will ensure that you take the shortest time possible from the US to Ireland, which reduces the likelihood of your kids getting weary before reaching their destination.
Consider the idea of staying close to DUB Airport if your aircraft from the US is slated to land in Ireland at night. When travelers arrive at DUB late at night, one of the nicest and closest locations to stay is The Maldron Hotel Dublin Airport. Being one of the nearest hotels to DUB, this hotel is just 1.1 kilometers away and is easily accessible by foot for travelers.
The majority of travelers who want to take the shortest time possible from the USA to Ireland should consider departing from either New York Stewart Airport (SWF) or Philadelphia International Airport (PHL). These are the major airports in the US that serve as hubs for airlines offering direct flights to Ireland.
