The carrier has five bases in Poland: in the northern city of Gdańsk, in Katowice and Kraków in the south, in the capital, Warsaw, and in the southwestern city of Wrocław.
Meanwhile, Polish national carrier LOT said on Tuesday it was calling off flights planned between March 29 and April 11.
The airline said the move came after the Polish government extended a suspension of scheduled passenger flights until April 11.
LOT added that until that date it would be operating only special flights chartered by the Polish government to bring citizens home from abroad amid the coronavirus outbreak.
The carrier said on Tuesday that some 32,000 Poles so far had returned to their home country on the special flights.
The government suspended scheduled international passenger air connections to Poland on March 15.
The country has declared a “state of epidemic" and temporarily closed its borders to non-residents in a move to curb the spread of the coronavirus.
Authorities reported on Tuesday that two more patients had died in Poland after contracting the virus, bringing the country’s death toll to 10. A total of 901 people have tested positive for the Covid-19 disease in Poland.
