Poland could drastically cut back on flights to and from Warsaw from 1 May if a dispute with air traffic controllers over pay and conditions is not resolved, according to legislation published before negotiations were set to resume on Tuesday 26 April.
Almost 90% of air traffic controllers in Warsaw chose to quit rather than accept new working regulations, which they say threaten safety. Some have already left and the notice period for the remaining 136 ends on 30 April.
This will leave Warsaw's two main airports with only 26 controllers between them and likely lead to mass cancellations of flights to and from Warsaw, but authorities said flights passing through its airspace should not be cancelled.
"Half of these flights will be made in our airspace, half of these flights... will be redirected to neighboring countries, but flights over Poland will not be cancelled," Civil Aviation Authority head Piotr Samson told journalists.
The government announced late on Monday in the official gazette that from 1 May, the Chopin and Modlin international airports would only be operational from 0930 to 1700 local time due to a lack of air traffic controllers. The legislation gave a list of flight destinations that would be prioritised.
Airlines affected would include LOT Polish Airlines, Wizz Air WIZZ.L and Lufthansa LHAG.DE, which all operate out of Chopin airport, and Ryanair RYA.I, which flies out of Modlin.
Ryanair said on Tuesday 26 April that it had complained to the European Commission about the legislation because it believes the list of prioritised destinations unfairly favours LOT.
"The Polish government has first mismanaged the pay dispute with Warsaw air traffic controllers and has now shown complete disregard for Ryanair passengers, choosing to protect non-essential LOT routes... at the expense of key Ryanair routes such as Stockholm and Milan," Ryanair chief executive Michael O'Leary said.
Among proposals seen as unacceptable by the union are a cut in air traffic controllers' pay, an increase from eight to 12 in the maximum number of hours they can work in a shift and the possibility for controllers to work alone.
The government says it has accepted the proposals on safety and that talks are now focussing on salary issues, but that the controllers' expectations are too high, especially given decreases in air traffic due to the COVID-19 pandemic.
The air traffic controllers' union says its safety concerns have not been adequately addressed and that the government is misrepresenting how much they earn.
