The Republic of Ireland is the independent EU nation covering most of the island; flights land at Dublin, Shannon, Cork, or Knock, and US citizens enter visa-free for up to 90 days. Northern Ireland — including Belfast — is part of the United Kingdom and has separate entry rules.

Belfast is in Northern Ireland, part of the United Kingdom, not the Republic of Ireland. US citizens flying into Belfast International (BFS) or George Best Belfast City (BHD) need a UK Electronic Travel Authorisation (ETA), not an Irish visa — even though there's no passport check when crossing overland between Dublin and Belfast under the Common Travel Area.

It depends on your nationality. US, Canadian, Australian, New Zealand, UK, and EU/EEA passport holders can visit the Republic of Ireland visa-free for up to 90 days for tourism or business. Citizens of India, China, Nigeria, South Africa, Kenya, and many other countries need a short-stay 'C' visa from the Irish Embassy before travelling. Ireland is not part of the Schengen Area, so its visa rules are separate from the rest of the EU.

A single-journey Irish 'C' visa costs around €60 and is valid for one entry of up to 90 days. A multiple-journey visa costs around €100 and can remain valid for up to 5 years, though each individual stay is still capped at 90 days within any 180-day period.

If your flight is cancelled on a route departing the EU (including Ireland) or operated by an EU carrier, you're generally entitled to a refund or rerouting, and possibly compensation, under EU Regulation 261/2004. Contact your airline immediately and keep all receipts for additional costs — these may be recoverable. Triwize's 24/7 customer support team can assist with rebooking and claims for bookings made through our platform.

Flight times vary by departure city: around 5 hours 55 minutes from Boston, 6.5-7 hours from New York, roughly 8 hours from Chicago, and 9-10.5 hours nonstop from the West Coast.
