Yes, I was thinking the same thing.. it's only one day off (Tuesday) but the Poles really love their long weekends and it seems as if the entire country has emptied (actually a great time to be in WAW).

In the end I resolved it by sending them a message via FB. They're very quick in acknowledging enquiries sent to them via Messenger but if you ask for information about IRROPS, etc., often the response is quite generic ('your flight has been delayed due to technical issues').

I also noticed that my M&M account has not been updated to show the KRK flight I took several days ago - usually it shows within 24 hours, so at the moment there's definitely a feeling of nobody home.
