I wanted to go and get it myself, but RyanAir won't let me carry it on board even if I pay an Extra Item Seat.
How come? Is it too big as carry on luggage or did they give you some other excuse?
Just looked at their figures, if it was inside a box it would prob be too big as carry on - by a few millimetres.
"Strictly one item of cabin baggage per passenger (excluding infants) weighing up to 10kg with maximum dimensions of 55cm x 40cm x 20cm is permitted."
But surely you could have bought a seat for it?
Try to convince them that its not a bomb.
