Depends where you are, really. In Europe, where Ryanair does virtually all their business, courts have generally been reluctant to take the "haha, you clicked on the website, you've magically agreed to the license" thing as being particularly meaningful, and recent regulations have cut down the usefulness of EULAs even further.
That said, Ryanair prices aren't login-walled anyway.
