I forgot to mention cabin crew based in Portugal.
Local media both in Catalonia and in Spain have been giving the strike a lot of coverage.
Catalan reports this morning spoke of last minute (sic) cancellations of flights to the Balearic Islands (which Ryanair had been ordered to maintain fully operational under Spanish labour laws which they had apparently agreed to do earlier) from both El Prat and Girona I seem to remember.
Elsewhere reports of last minute cancellations of one or more flights to Italy.
The disastrous record of Vueling at El Prat in the last 10 days [at least?] also got lots of air time
