Hm. I thought that I'd tried that. What incompetence on the part of Ryanair (no matter how much I dislike Ryanair, as they are masters of pushing flyers to self-service, I am surprised that they make this one too difficulty). I wonder whether it would have showed accurate data, anyway?
Of the various flight tracking websites (FlightRadar24, FlightAware, etc, etc) only some showed the delay on the day of the flight; some others persisted in showing "on-time".
(Also, heh, the first flight plan Ryanair filed showed departing on time [despite that the flight plan was filed seven hours later] and arriving at the actual middle-of-the-night in Barcelona - so, EDI-BCN scheduled for 12 hours flight time..... heh)
