The airlines affected by the diversions have called for more action from the aviation authorities and said the latest disruption was unacceptable.
In a statement, Ryanair boss Michael O'Leary said: "It's unacceptable that more Ryanair flights and hundreds of passengers have again suffered disruptions and diversions as Dublin Airport is now closed for a sixth time in six weeks by drones.
"Transport Minister Eamon Ryan has failed to take any effective action to protect Dublin Airport and his strategy of holding "meetings" is useless. As always Minister Ryan promises "stronger measures" but delivers nothing.
"Minister Ryan should explain why other European airports have effective drone measures in place but Dublin Airport keeps being closed."
Aer Lingus said: "A step change in urgency is required from the key stakeholders charged with managing this critical issue (Dublin Airport, the regulator and Department of Transport).
"Processes and technology are urgently required to prevent these events happening in the first place and to minimise the disruption if they do happen.
"This is the third drone incident in a matter of weeks, creating a level of disruption that is both concerning and unacceptable."
