Spanish air traffic controllers have called off a planned three-day strike next week that would have halted flights and hit hundreds of thousands of holidaymakers.

The controllers’ union UNSCA postponed the strike over pay and conditions following an outcry from Spain’s tourism industry, which called on the government to intervene.

However, the dispute remains unresolved after talks between the union and airports authority AENA broke down last Friday, and the threat of strikes remains from September.

A UNSCA spokesman said: “The union understands the concerns of the tourism sector and passengers.”

Strikes at UK airports, including Heathrow and Stansted, remain a threat this month. The Unite union is due to announce the result of a strike ballot over pay among firefighters, ground-handlers and other staff at BAA’s six UK airports tomorrow.
