Aer Lingus has cancelled 22 flights today due to the dispute with cabin crew over rosters.
The company said 1,000-1,500 passengers could be affected by the cancellations. The cancelled flights are mainly from Dublin to British and European destinations. However, one Shannon-Heathrow service will also be cancelled.
Aer Lingus cancelled 20 flights yesterday.
The dispute with cabin crew, who are represented by the Impact trade union, has been under way for over a fortnight. Aer Lingus says passengers are being notified in advance of flight cancellations and accommodated on other services.
The airline has also advised passengers to check its website for information.
Fine Gael's transport spokesman Simon Coveney said the airline has a responsibility to end the dispute and called on Minister for Transport Pat Carey to intervene. "As I have said many times during this dispute, the travelling public is being treated with disregard and disrespect by an airline whose successful history has been based largely on customer service. It's about time we saw Aer Lingus prioritising its customers by putting an end to a long-standing dispute and making the talks work today.
Meanwhile, talks at the Labour Relations Commission, aimed at providing a resolution to the dispute, continued last night. Informed sources said some progress was being made on working through the issues involved in the dispute.
Some sources also suggested that chief executive of the Labour Relations Commission Kieran Mulvey could be asked to produce a report on the issue as early as today. Mr Mulvey last summer produced a comprehensive arbitration document on the issue of rosters at Aer Lingus.
More than 300 cabin crew have been taken off the payroll by Aer Lingus management for refusing to operate the controversial new rosters, introduced unilaterally a fortnight ago.
Seven cabin crew who were taken off the payroll have been invited to attend disciplinary meetings with management today. The disciplinary meetings are the next stage in a process which could ultimately see staff dismissed.
