Ryanair have done the best thing by not flying into or out of Spain Today
You may have a different view if you had a booking on one of the cancelled flights.
you will find alot of Airlines have canclled flights into and out of Spain today IB, KLM, FR, EZY to name afew.
True, but Jet2 operated EVERY flight to Spanish destinations from Manchester today. Late yes, but they are getting their passengers to their destinations, not simply saying p$ss off go and rebook your flights.
