From 1st November, unless you pay for priority boarding with Ryanair (£5 per person), you won't be able to take your wheelie bag (up to 55cm x 40cm x 20cm) into the cabin. They will be taken from you at the gate and placed in the hold (free of charge).
You will only be allowed a smaller bag, like a handbag (35cm x 20cm x 20cm), on board.
However, they have increased the hold luggage from 15kg to 20kg and reduced the price from £35 to £25.
