United Airlines is offering a travel waiver for eligible flights involving Dublin Airport on Nov. 11 and 12. The airline lists Nov. 15 as the final day for replacement travel under its Ireland industrial action waiver. That gives travelers on qualifying United bookings, including U.S. itineraries such as Newark to Dublin, an option to move their flights.

United's waiver guidance says travelers may avoid a change fee and any fare difference if they keep the same origin, destination and cabin, and rebook on a United or United Express-operated flight within the permitted dates. Check the price shown for your ticket before confirming the change. If a travel agent booked it, ask the agent to check the Dublin waiver, listed as 7JC98.

Allow extra time to reach Dublin Airport

The rebooking window and the road restrictions cover different dates. Ireland's National Transport Authority says travel around central Dublin may be disrupted through Friday, Nov. 13, because of two European Union presidency meetings. It advises passengers headed to Dublin Airport to allow extra time. Some city bus routes and Luas Red Line services are affected.

Check your flight in United's My Trips. If you plan to keep the booking, check your ground route separately before leaving. The airline waiver does not establish that your flight has been canceled.
