Looks like Modlin will be closed to B737 and A320 size traffic, I.e Wizzair and RyanAir for several months now.
Effective 15:30 today, Dec 22, the main runway was shortened from 2,500 to 1,500 meters due to surface problems, which now need to be fixed under warranty by the original developer. As a result pretty much all traffic has been diverted, most to WAW
some to Lodz.
