European flights back to normal Wednesday - Eurocontrol
Areas of high ash concentration at lower altitudes were, however, still causing some difficulties for trans-atlantic flights as well as for Madeira and the Azores.
This could result in airport closures in the Mediterranean between the Spanish mainland and the Balearic Islands, Eurocontrol said, adding the ash cloud was moving north east.
All airports were available, but the Balearic islands airports were operating at reduced capacity, Eurocontrol said.
