Once you have reported your checked-in bag as damaged/delayed/lost at your arrival airport and have received a Property Irregularity Report (PIR), you can submit a claim form to Ryanair. You can find this baggage claim form here. The 10-character file reference found on your PIR Report must be included when making your claim. This reference is located at the top of the report (EG. STNFR12345). Claims cannot be processed unless the case has been reported at your arrival airport and a PIR has been issued.
