In this current crisis, some insurers responded quickly and responsibly. For example, automatic policy extensions were granted to Israelis stranded abroad, sometimes for up to seven days. Still, the core issue remained unchanged: most policies exclude acts of war. A canceled flight due to closed airspace might entitle you to a voucher or refund. However, if you were forced to remain in a hotel, compensation is unlikely. Additional expenses, such as food, lost bookings, or transportation, will typically not be covered.
