Aer Lingus has said that some of its customers flying to Brussels are experiencing “some disruption” as a result of a strike by baggage handlers at the airport this week.
It has been reported that the four-day protest left as many as 20,000 pieces of luggage stranded at Belgium's largest hub.
An Aer Lingus spokesman said that bags destined for Ireland should be re-united with their owners before the end of today.
However passengers who travelled from Dublin to Brussels may have to wait another day or two before their luggage is returned.
Aer Lingus said most of its customers were not affected by the dispute, as a high proportion of them on the Dublin to Brussels route only travel with hand-luggage.
The strike was the longest of its kind at the airport in Zaventem, northeast of Brussels.
Airport spokesman Jan Van der Cruysse said returning all of the luggage would be hard work.
He said: "That's going to be a hell of a job. Everything will be returned, but it might take a few days."
