Thousands of people were suffering the consequences on Monday of a 24-hour strike of pilots and cabin crews at Italy’s flagship carrier Alitalia, according Euronews.

The strike hit the airline’s entire network, except for operations at Bari, Brindisi and Genoa. The ANPAC union is asking for the company to confirm in writing that jobs won’t be lost when a solidarity contract expires in February.

Alitalia cancelled 130 flights and attempted to contact 12,600 passengers to offer alternative flights or refunds, but many of them were not reached in time.
