Ryanair announced last month a wave of flight cancellations caused by a shortage of pilots. It is expected to affect more than 700,000 passengers over the coming months.

ENAC Chairman Vito Riggio and Managing Director Alessio Quaranta met with Ryanair Chief Executive Michael O'Leary and Chief Commercial Officer David O'Brien on Thursday to discuss how the carrier handled the cancellations, ENAC said in a statement.
