Italy's airlines are experiencing a "general state of suffering" in financial terms and require supervision to ensure their continued stability.
The country's civil aviation regulator ENAC delivered the verdict at a board meeting on 21 January, as part of an ongoing probe into the health of the nation's air transport sector.
It says that while the day-to-day operations of the airlines has yet to be compromised, their economic plight merits increased vigilance "aimed at maintaining the financial conditions of the operators".
ENAC will continue its investigations, it says, and will shortly hold hearings with management from Italy's major carriers.
Airlines Blue Panorama and Meridiana Fly are operating with monthly permits at present after financial problems prompted ENAC's intervention.
