I couldn't agree more with Dan's opening post of this thread.
Even if the Spanish controllers have an axe to grind over industrial issues, I can't see how being so obstinate ,petulant and unprofessional should in any way help their cause with their employers.
Its just costing my employer and all the other airlines who have to fly in Spanish airspace, a lot of extra money in fuel. Why would the Spanish authorities give a damn about that ?!
Oh, and another thing .... - Maybe if the Spanish hadn't blown it big time and squandered the Billions they've received from the member states of the EU, who's airines the Spanish controllers are now targeting, then there wouldn't be a need to have their terms and conditions altered in the first place.
How about maybe trying to find a scape goat issue to deflect attention away from the sorry state the Spainish state is now in - like, say Gibraltar for example ! Oh yeah, already been done......
