Thousands of passengers impacted.
Aer Lingus has been forced to cancel all their scheduled flights from Dublin Airport to all European and UK destinations this afternoon.
The airline is having a technical problem with its reservation and operational systems.
This is causing check-in and boarding disruption.
It is thought that thousands of passengers are impacted, with queuing building for metres outside the Terminal 2.
Please note, @AerLingus have requested that any @AerLingus passengers due to fly on any of their cancelled services today should NOT arrive at Dublin Airport.

The Aer Lingus website remains inaccessible, with a temporary image saying it's undergoing a 'scheduled upgrade.'
It's expecting delays and disruption to services, for several hours.
The company is apologising to passengers for the inconvenience, and says its working to solve its connection issues as soon as possible.
