From 01MAR until 31MAY Basia will offer free juice, wine and beer in Y on MAD, BCN, IST, PAR and AMS. It’s a trial.

With the exception of MAD and BCN, where Basia has no legacy competition, the competitors on AMS, CDG, PAR and IST all offer the same service. I wonder if it will cover KRK-IST or only WAW.
