The only way i could see Milan and Verona remaining is if another airline took them over. Maybe TUI for Verona or someone elsewhere suggested Volotea for Verona and Venice. Maybe Air Italy for Milan? Ryanair for Rome maybe? But i doubt very much any of the Italian routes will be operated by Flybe.
What will be interesting is too see how and if the airport manage to salvage many of the lost routes especially the Italian ones.
