Ryanair recently announced suspension of Italian Domestic flights MIPC provided alternative flight options. Anyway the problem has been resolved and Italian Domestic flights will resume so the panic is over as ENAC agree to maintain official ID for internal flights. Read the press release here.
One good outcome of this recent issue is that 2 further airlines considered increasing their Italian domestic flight schedules. This is particularly good for Trapani airport TPS which until now has been offering exclusively Ryanair flights. It now means that flights to Trapani Sicily will increase and continue to drive tourism in Sicily.
