Ryanair has said it expects up to 100 flights could be cancelled across its European network due to this weekend's French air traffic control strike.
The airline said that currently just one flight has been cancelled from Ireland at this time - the Dublin to Nice service on Saturday.
In a statement the airline added that it expects the principal impact for Irish customers will be flight delays.
The airline repeated its call for "urgent action" to prevent a "full meltdown" of ATC services this summer.
Ryanair said yesterday that it cancelled just over 1,000 flights last month which were "almost all due to ATC staff shortages and strikes".
Passengers are being advised to check with their airlines to see if their flights are affected by this weekend's strike.
A spokeswoman for the Dublin Airport Authority said it is unknown how much the strike is set to affect flights.
The spokeswoman advised passengers to check with their airline before traveling to minimise disruption.
Flights which fly over France without taking off or landing in the country will also be affected by the strike.
Aer Lingus has advised customers to check the status of their flights before departing for the airport.
The airline has said customers facing disruption can change their booking online or apply for a full refund.
The strike by ATC staff will last through the weekend until Sunday 17 June.
