Pilots with German airline Lufthansa have extended their strike action by another 24 hours in a long-running pay dispute.
It is the pilots' 14th strike since April.
Around 1,800 long- and short-haul flights will again be grounded today, including eight scheduled Frankfurt and Munich flights to and from Dublin Airport.
Tomorrow, the walkout at one of Europe's largest airlines will affect only short-haul flights. The airline's Dublin Airport flights will again be impacted.
The Vereinigung Cockpit (VC) pilots' union had planned a 24-hour walkout yesterday but late on Tuesday said it would be extended to today after two courts rejected attempts by Lufthansa to halt the industrial action.
"Lufthansa management has shown no sign that it is willing to move and has not provided an offer that could serve as a basis for negotiations," VC board member Joerg Handwerg said.
Lufthansa, led by CEO Carsten Spohr, insists that despite a record profit in 2015, it has no choice but to cut costs to compete with rivals such as Ryanair on short-haul routes and Emirates on long-haul flights.
Lufthansa's CEO has said he expects the strike to cost between €7 million and €9 million a day.
The airline has called on the pilots to enter mediation, which has been rejected by their union because it is seeking a better offer from management first as a basis for talks.
The union wants an average annual pay increase of 3.7% for 5,400 pilots in Germany over a five-year period from 2012. Lufthansa has offered 2.5% spread over six years to 2019.
In its effort to reduce costs, Lufthansa has agreed deals on pay and retirement schemes with the main unions representing ground staff and cabin crew in Germany.
A pilot at Lufthansa earns on average €180,000 a year before tax, though a captain on the highest pay level can earn as much as €22,000 a month before tax.
Meanwhile, planned strike action today by pilots at Cityjet has been deferred following talks at the Workplace Relations Commission yesterday.
The Unite trade union, which represents the pilots, says it agreed to the move to allow for a Labour Court hearing into its ongoing pay dispute.
The Commission also urged both parties to engage in local discussions aimed at progressing some other outstanding issues.
