Travellers to Spain face disruption this month with two strikes planned by Air Traffic Controllers.
Industrial action is set for this weekend, July 11 and 12, and for the weekend of July 25 and 26.
The walkouts follows a long-running dispute that goes back to 2010 and the dismissal of a controller in Santiago de Compostela for his role in wildcat strikes of that year.
Easyjet said that, like all airlines operating flights to Spain, if the action goes ahead it expects to see an impact on its services.
In a statement, the carrier said: "We would like to assure our passengers that we are preparing for any disruption if the strike does proceed and will do everything possible to limit the inconvenience of this on your journey."
Spanish air traffic control service Enaire expects to operate 80 per cent of services during the strike periods while talks continue with the USCA controllers' union.
