Some commercial flights into the international airport in Catania, Sicily, are being diverted to the shared Italian-U.S. Navy military base at Sigonella for the next 30 days during runway renovations, officials said.

The military base is prepared to accommodate upwards of 72 flights a day. The Catania airport’s runway is slated to be closed through Dec. 5, said Lt. Col. Salvatore De Maio, a spokesman with Italy’s Defense Ministry.

U.S. Navy and Italian officials said they are not anticipating any disruption to routine military operations at the base. A gate on the Italian side of the base, normally closed to traffic, is being used for buses chartered by the Italian airport authority to ferry commercial airline passengers.

Passengers are asked to check in three hours before their flight and will go through regular check-in and security procedures at the commercial airport before boarding chartered buses to the military base.
