I don't know if I have mis-read it but the following airports still remain accessible to GA visitors
Bilbao, Fuerteventura, Girona, Ibiza, Lanzarote, Menorca, Santiago, Sevilla,
Tenerife Norte y Valencia Almería, Asturias, Coruña, Granada-Jaén, Jerez, La Palma, Murcia, Reus, Santander, Vigo y Zaragoza, Albacete, Algeciras, Badajoz, Burgos, Ceuta, Córdoba, Cuatro Vientos, Hierro, Huesca, La Gomera, León, Logroño, Melilla, Sabadell, Salamanca, San Sebastián, Son Bonet, Pamplona, Torrejón, Vitoria, Valladolid.
(though PPL training is going to cost a lot more there) and the ones which have gone bonkers are
Madrid-Barajas, Barcelona, Alicante, Gran Canaria, Tenerife Sur, Málaga, Palma de Mallorca
It's a pity. It looks like the European big-airport managers have all got together to compare notes...
