Lufthansa flights are being grounded again tomorrow due to an ongoing strike by pilots.
Eight services have been cancelled in and out of Dublin Airport to Frankfurt and Munich yesterday and today, and now further disruption is expected on Friday.
Tomorrow's walkout will affect only short-haul flights.
It is the pilots' 14th strike action since April 2014 in their row over increased pay.
Intending passengers are advised to check their airline's website before travelling to the airport.
