No C class check-in for SWISS Airlines although according to SWISS there should have been. Check-in staff extremely rude and unhelpful. Security checks : 5 people for one belt/machine. I inadvertently had two litre bottles of water in my hand-luggage together with two toilet bags full of liquids that I forgot to take out. All these went absolutely unnoticed which confirms the comments from a security agent on a previous trip not to bother putting my hand- luggage on the belt as the x-ray machine didn't work. Warsaw is not for the faint-hearted.
