It's good news that they have resumed their flights - but one thing we have found flying with Ryanair is that their insurance is not worth adding to the flight cost. If they fail to get you on a flight they are obliged to put you on the next flight or the next convenient flight. If you then claim because you missed onward connections, which is covered by their insurance, it is not possible to get the right documentation from Ryaniar to satisfy Ryanair's insurance department! To explain - the insurance department requires a form from Ryanair. Ryanair sends out the wrong information. The insurance department requests the correct information. Copy sent to Ryanair. Ryanair send out the wrong information. After repeating this 3 times- gave up.
However, they are cheap and convenient and you can not accept the charge for their insurance.
