Well Im ex ezy and it was quite unbelievable!!
Even though there is no weight restriction there is a size restriction.
Most check in agents especially in Italy and Spain are unaware of this rule and often we would get some wierd things coming on board.
Apart from the usual passenger trying to bring 5 or 6 bags on (yes 5 or 6 bags!!!) I have had a passenger bringing a statue of board, paintings and a 5ft plant!!
