Ryanair have now cancelled most flights to Spain up to & including Thursday - see copy & paste fom Ryanair website below:
In response to the decision of the Spanish Government to “lock down” the entire country to contain the spread of the Covid-19 virus, Ryanair Group Airlines (including Buzz and Lauda) has been forced to severely reduce flights to/from Spain, the Balearic Islands and Canary Islands from 24:00 Sun 15 Mar until 24:00 Thurs 19 Mar. We are contacting all affected customers by email to advise them of their options and we urge customers not to call us.
For cancelled flights, you have the option to take a refund or change to another flight for no charge (unless the other flight is more expensive, in which case you need to pay the difference). Or, if your flight isn't currently cancelled, you can change as above.
