TEHRAN (Press TV) — Italy is set to ban flights by Iran’s Mahan Air, the country’s second largest airline from its airspace in December.

Italian civil aviation regulators have limited the authorisation of Iranian carrier Mahan Air, cutting off its route permits just a month and a half into its winter schedule. National regulator ENAC states that the airline will only be allowed to operate until 15 December.

ENAC has not given a reason for its decision, stating only that Mahan Air flights are authorised “only for a limited period”. The regulator says this will give the carrier time to rebook affected passengers.

Mahan Air operates to Milan Malpensa and Rome Fiumicino from Tehran’s Imam Khomeini airport. It had previously been serving Milan but only commenced the Rome service in early July, the airline says.
