Below you will find the information on the regulations regarding the conditions of crossing the Polish border.

From March 28, 2022, pursuant to the provisions of the Regulation of the Council of Ministers, all pandemic restrictions regarding travel to Poland are lifted, which means that there is no longer any obligation to present vaccination certificates when crossing the border, make SARS-CoV-2 tests or undergo entry quarantine.

Lifting of the obligation to wear facemasks

From March 28, 2022, covering the mouth and nose at our airport is not obligatory, but we still recommend using facemasks.

The rules for wearing masks on board airplanes will be regulated independently of the regulation by the airlines.

Due to the changing sanitary conditions and regulations, both at home and abroad, we advise you to verify the currently applicable restrictions before each flight (on the day of departure).
