The air traffic controllers' union in Europe (ATCEUC) has called off a strike planned for October 10 after the European Commission indicated its willingness to renegotiate changes to civil airspace plans.
The union has said it opposed the commission's plans to set "unrealistic" targets for air traffic management by 2019 because the goals seek a tenfold increase in flight safety while cutting costs by 50 percent.
The ATCEUC, which represents 14,000 air traffic controllers in Europe, said in a statement on Friday that it would renew its plans for industrial action if talks failed to address its concerns.
"ATCEUC will not be satisfied just with signs of good will and nice words. We expect clear outcomes and results," it said.
A strike would risk disrupting travel across Europe.
ATCEUC represents air traffic controllers in 26 countries including Italy, Belgium, Germany, France, Italy and Spain.
