No disruptions to flights on final day of Spanish air traffic controllers' 4-day strike

Spain's air traffic controllers say the final stretch of a four-day strike has seen no flight disruptions because none of their operators left their posts.

Controller stoppages had been scheduled for between 10 a.m. and noon and 6 p.m. and 8 p.m. on Sunday to protest against penalties imposed on members who held a strike in 2010.

However, "not one controller left his post" their official Twitter account said before the final two-hour stoppage was due to begin.

Airport authority AENA and Spain's air navigation company, Enaire both confirmed flight activity was normal except at Valencia airport that had been buffeted by "adverse meteorology."

In December 2010 controllers staged a 24-hour wildcat strike over work conditions that closed Spain's airports and left 600,000 travelers stranded just before a national holiday.
