Mateusz Morawiecki, the prime minister, has appealed for compromise between protesting air traffic controllers and the state air navigation agency PAZP as Warsaw faces severe flight cuts.
Representatives of the air-traffic controllers trade union (ZZKRL) and Poland's Air Navigation Services Agency (PAZP) are set to meet again on Tuesday, the two announced in a joint statement, in an effort to avoid a closure of airspace that could lead to severe disruption to air travel in Poland.
A striking air traffic controllers' union is demanding a pay rise to an average of PLN 80,000 (EUR 17,210) a month from the current PLN 33,000 (EUR 7,100), the Polish government's spokesperson has said.
A further round of talks is scheduled to start at 14:00 on Monday between Poland's Air Navigation Services Agency (PAZP) and the striking ZZKRL traffic controllers' union, the two parties announced in a joint press release following talks on Sunday.
Up to 300 flights over Polish airspace may have to be rerouted and many flights to and from Poland cancelled if an ongoing dispute between air traffic controllers and aviation authorities is not resolved soon, the Eurocontrol agency told PAP on Friday.
Failure to reach an agreement between the Polish Air Navigation Services Agency (PAZP) and air traffic control unionists, by Friday, may result in large-scale flight cancellations, an aviation official said on Thursday.
Poland's Civil Aviation Authority (ULC) has posted on its website a warning of possible flight delays and cancellations at Warsaw's airport due to a protest and some flight controllers quitting their jobs.
