As Antonio, I can't understand such savage strike (think it is in summer, where Iberia has the most of its flights). They are very well payed people, so it is not understandable to go to strike to claim a 12% increase of salary.

They are doing a lot of damage to the tourism and to the customers :-(

Anyway, they are going to strike on July's tuesdays and August's mondays.

Regards.
