Aer Lingus has direct flights that fly to Dublin and Shannon Airport. Dublin Airport is located in County Dublin which is about a 1 hour and 45 minute drive from Lough Rynn. Shannon Airport is located in County Clare which is about a 2 hour and 30 minute drive from Lough Rynn. Dublin is the Capital of Ireland and has a bunch of fun things to do! We highly advise keeping an eye out on flights starting in September of 2025 - August of 2026 as the prices can vary. You can also download the Hopper App which predicts when prices might lower. Both Airports have busses and car rental's that take you to County Leitrim which I have added sections on below!
Delta Airlines also fly to Shannon and Dublin Airport, although some of their flights have layovers.
JetBlue also flies to Shannon and Dublin with connecting flights.
