From 01/11/2017 Ryanair will be changing their baggage policy. This is mainly to encourage passengers to check in bacgs and reduce the carry ons which should reduce boarding delays.
The new allowances are as follows
The check-in bag allowance will increase from 15kg to 20kg for all bags
The standard check-in bag fee will be cut from €/£35 to €/£25 for this 20kg bag
Only Priority Boarding customers (including Plus, Flexi Plus & Family Plus) will be allowed to bring two carry-on bags on the aircraft
All other (i.e. non-priority) customers will only be allowed to bring one smaller carry-on bag on board the aircraft, while their second (bigger) wheelie bag must be placed in the hold (free of charge) at the boarding gate
