Flew back from Poland with Whizz a few weeks ago, their hand luggage allowance is half the size of ryan airs and must fit into the cage before boarding, anything bigger than a small backpack then they sting you with a 40 euro charge. Nae suitcases whatsoever. They give you a tag for "small" hand luggage or "large" hand luggage when you pass security and if you get given the large sticker theb you better hoped you have paid for it in advance. Saw a few pissed off people get lumped with the charge at the gate.
