Yes, September 2023 saw significant industrial action across Italy's aviation sector. On September 8, 2023, a major 24-hour nationwide strike was held by ground handlers and airport staff, leading to the cancellation of hundreds of flights, including over 30 domestic flights by ITA Airways. Another general strike occurred on September 29, 2023, affecting various transport sectors including air travel. These strikes are common in Italy and are typically announced well in advance. Under Italian law, certain "essential" time windows (usually 7:00–10:00 AM and 6:00–9:00 PM) are protected, meaning flights scheduled during these hours must proceed as planned. Travelers during such periods are generally advised to check with their airlines 48 hours in advance for rebooking options or status updates.
