Ohh sorry, I was wrong, just seen this :
All passengers must present valid photo identification at check-in for all flights. The only acceptable forms of photo-ID on Ryanair flights are:
: A valid passport
: A valid Government issued National Identity Card issued by a European Economic Area (EEA) country. Only the following countries from the EEA issue National Identity Cards which are acceptable for carriage: Austria, Belgium, Finland, France, Germany, Greece, Cyprus, Czech Republic, Estonia, Hungary, Italy, Liechtenstein, Lithuania, Luxembourg, Netherlands, Malta, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden (for travel within the Schengen area only) and Switzerland.
: National Identity Cards issued by the Government of Gibraltar.
: A valid European Economic Area (EEA) driving licence with photo, presented by a passenger whose place of birth is within the EEA is acceptable only for travel on internal flights within the UK, internal flights within Italy and UK-Republic of Ireland-UK.
In accordance with Article 28(1) of the 1951 UN Convention, a valid UN Refugee Convention Travel Document issued by a Government in place of a valid passport is acceptable.
