IAG's low-cost airline Iberia Express has confirmed the cancellation of 12 flights after cabin crew union USO announced a 10-day strike starting 28 August, while the union said that 92 flights had been cancelled in total.
USO, the union representing 532 of the airline's cabin crew, said the 92 cancellations would mainly affect flights within Spain, and around 17,000 passengers.
It condemned the decision to scrap flights rather than seek a resolution to the dispute over working conditions. "This decision makes it clear that the airline is aware of the discomfort of its staff, however it does not come with proposals to the meetings," union delegate Estefania Diaz said in a statement.

Iberia Express said it was cancelling 12 flights on 28, 29 and 30 August, with a spokesperson insisting that no decision had been taken yet for flights scheduled for the remaining seven days of the strike.
"These cancellations are intended to minimize, above all, the impact on our customers," the company said in a statement.
"We make a new appeal to the responsibility of the 'USO' union to call off the strikes and bet on dialogue and not social confrontation."
The labour dispute arose amid the travel industry's turbulent post-pandemic recovery as cabin crews and pilots of several airlines across Europe demand better working conditions and higher wages to offset inflation.
Iberia Express connects Spain's capital with about 40 cities all over Europe.
