Hi all, I have rimowa aluminum case of cabin plus size (57cm x 44cm x 25.5cm). It is very obvious that this won't pass the sharp eye of the ryan air staff to be carried into the cabin. I don't mind the option of paying extra to get it checked-in but even the size restriction for check-in luggage is same as the cabin one 55 x 40 x 20. Do you know how strict they are for check-in luggage? If I don't have any better option, mind as well fly with different airline.
