Frequently Asked Questions

How cheap can flights to Ireland get?

Error fares and sales regularly bring roundtrip fares under $350 from East Coast cities. Aer Lingus's regular sales often offer $399-449 roundtrip from multiple US cities.

What is US preclearance?

US preclearance at Dublin and Shannon airports means you go through US immigration and customs before boarding your flight home. When you land in the US, you walk straight out — no immigration lines.

Should I fly into Dublin or Shannon?

Dublin has more flight options and cheaper fares. Shannon is ideal if you're headed to western Ireland (Cliffs of Moher, Galway, Ring of Kerry). Consider flying into one and out of the other.
