We recommend flying with Aerlingus If traveling from the United States. They offer direct flights into Shannon on the West Coast or Dublin on the East Coast. Shannon airport is more accessible to County Galway (Wedding location). However, you can also choose to fly into Dublin and get transportation from Dublin to Galway pretty easily via bus. 
Aerlingus typically offer a sale in May for the upcoming October season so we would recommend waiting until April/May 2024 to get the best value for your money on flights - typical fair price at this time is around $500 per person from Boston to Shannon
