Passengers arriving at Dublin Airport tomorrow face disruption, as taxi drivers are refusing to pick up at the airport in a dispute over parking spaces.
Drivers have said that the row, which began today, will resume tomorrow and may escalate.
Two meetings were held today between taxi representative groups and the Dublin Airport Authority, but an agreement was not reached.
Taxis are dropping people to the airport but are not collecting anyone from arrivals.
The row centres on a reduction by around 70 spaces in the taxi holding area of the airport.
The DAA has said the reduction was for commercial reasons.
It said it regrets the inconvenience to customers resulting from what it calls a "unilateral" action.
The DAA said it offered to reinstate 30 of the 70 spaces, but this offer was rejected.
