Delta does not currently operate nonstop flights to Ireland. Travelers looking to fly from the U.S. to destinations like Dublin or Shannon would need to connect through another European hub or book with a partner airline. Routes and schedules can change seasonally, so availability may vary depending on the time of year. If you’re planning a trip, it’s a good idea to check Delta’s latest route map or search for flights to see current options, including any codeshare connections that may get you to Ireland with one stop.
