People here sometimes ask for hard-to-discover addresses. Just for future reference, here is a letter copied from today's Grauniad with Ryanair's address:

•?It is ironic that Ryanair, which owes its rapid growth to EU competition law, should now object to consumer protection law from the same source. However, the law is clear. Ryanair is responsible for reasonable hotel and refreshment costs of passengers affected by the volcanic ash. While it is clearly banking on people feeling it is not worth the effort to lodge claims, the new European small claims procedure is straightforward for claims under €2,000, with the relevant information on the web page of the European Judicial Atlas in Civil Matters and the UK courts services. The process is slightly complicated by Ryanair's unwillingness to provide its registered address: Ryanair Customer Standards, Corporate Head Office, Dublin Airport, Co Dublin, Ireland.

Apparently if Ryan Air was registered in the UK, it wouldn't be able to operate its service the way it currently does because it would be in breach of UK air operating regulations. Apparently.
