Aer Lingus is to cancel 20 flights tomorrow as a result of the current dispute involving cabin crew at the airline over rosters.
The airline said that among the flights to be affected tomorrow will be one service to Boston. All the other routes to be hit are UK and European destinations.
The company said that there are now around 300 members of cabin crew off the payroll for refusing to operate controversial new rosters which it introduced unilaterally a fortnight ago.
Meanwhile, talks between airline management and the trade union Impact, which represents cabin crew, are continuing at the Labour Relations Commission.
The talks broke up on Friday without agreement but both sides kept in touch with the commission over the weekend and held discussions into the early hours of this morning.
The dispute over rosters is in now in its third week. Almost 300 cabin crew have been taken off the payroll and dozens of flights have been cancelled in the dispute.
The airline said yesterday bookings had started to suffer as result of the row. Aer Lingus has leased aircraft and crew from other airlines, including rival Ryanair, to continue its operations during the strike.
Separately, the airline said that all its flights to continental Europe from Dublin will operate from the new T2 terminal at Dublin airport from tomorrow.
