"There may be delays to your flight, please consult your airline for any further updates. We apologise for any inconvenience caused," a statement said.

In response to the airport's announcement on X, they said: "Really I'm still sat on a plane on the tarmac. Been nearly 3 hours now."

Another said they were hoping to board their flight soon as there was a "full Ryanair flight sitting here at Dublin Airport since 1.30pm".

As the airport announced the power failure affecting Air Traffic Control, one passenger commented on Facebook saying they had "been stuck on the plane in Szczecin airport for over two hours now," with "no updates" on the situation.
