Ryanair's new baggage policy comes into effect today.
It means passengers will no longer be able to take larger items of hand luggage on to the plane free of charge.
Up to now Ryanair didn't charge for smaller suitcases weighing up to 10 kilos.
But from today, passengers are being charged 8 euro, and they'll have to be checked into the hold.
People who don't pay when booking online, could be charged up to 25 euro at the airport.
However, Priority Boarding customers who pay just 6 euro will still be allowed to bring their larger hand luggage into the cabin.
And all passengers are allowed a handbag or laptop bag free of charge.
