Aer Lingus has said its website, mobile app and self-service kiosks are now fully available for customers to check-in and manage their bookings.
This follows a temporary issue earlier today when the airline's website and mobile app were down.
Aer Lingus also said all of its flights are operating as normal today.
Around 485,000 people are set to pass through Dublin Airport this Easter weekend, making it the busiest weekend of the year so far.
