EasyJet faced another walk out by pilots based in Amsterdam this morning.
The latest in a running dispute forced the budget airline to cancel some flights.
The VNU pilots’ union announced the industrial action with little advance notice, according to the airline.
The strike was taking place between 5am and 10am local time today.
EasyJet said: “This is the third strike the VNV have announced and we have been given only a few hours’ notice which makes it impossible for us to arrange alternative flying arrangements.
“Whilst we try to minimise the impact of the strike on our customers, unfortunately we will have to cancel some of our flights. We very much regret this.”
The airline added in a statement: “We have been working closely with the VNV to negotiate a collective labour agreement and are very keen to find a solution.
“Our latest offer represents a significant improvement compared to earlier proposals so it is disappointing that this unnecessary action will affect our passengers travelling through Amsterdam.”
