Ryanair is accused of breaking EU law because it is failing to tell customers whose flights have been cancelled about their right to compensation.

An email sent by the budget airline to affected passengers to inform them of their options does not mention the word compensation once, with the link to its compensation policy buried at the bottom of the email.

A link at the bottom of the email invites the recipient to click to view their "passenger rights", and contains details of redress they may be entitled to.

Under EU rules called Flight Compensation Regulation 261/2004, airlines are obliged to provide clear written notice to customers of their right to compensation, and how to claim.
