Ticket prices to Italy's two main islands have soared in recent weeks. Companies including Lufthansa (LHAG.DE), EasyJet (EZJ.L), American Airlines (AAL.O) and Delta (DAL.N) are members of the IBAR, the association's website shows. Measures in a decree law take effect immediately, but parliament has to ratify them within two months, otherwise they lapse.
