Ryanair will temporarily stop domestic Italian flights at 10 airports from Jan. 23 because of a row with regulator ENAC over check-in documents, the airline said.

The airline objects to ENAC's decision to cut requirements on documents that passengers have to present. The airline argues the new requirements will not provide a secure form of identification, it said in a statement.

"It is incorrect for ENAC to introduce measures that reduce security on domestic Italian flights compared to security measures used successfully on all other EU and domestic flights operated by Ryanair in other EU countries," it said.

Ryanair said the documents which ENAC had approved for identification include fishing permits and company IDs and that under the November decision Ryanair personnel are subject to arrest if they don't accept these documents at check-in.

Italy is one of Ryanair's major markets and the 10 bases where flights would be stopped include Bergamo, which serves Milan, and Rome's Ciampino airport.
