Flight from Washington Dulles Airport to Dublin

DaveFlew with Aer Lingus-Sep 2026

The Dublin Airport has NO rail service, so if making a rail connection, solid plans need to be made beforehand about where to go and how to get there.

IsabellaFlew with United Airlines-Sep 2026

My only tip is to put a small bag underneath bc you won't have room for much else.

Mary MargaretFlew with Aer Lingus-Jun 2025

Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.
