A deadly attack on Saudi Arabia's King Khalid International Airport in Riyadh, the country's second busiest, last week killed at least 13 people and injured over 300, highlighting the widespread impact of Middle East conflicts on air travel. The attack forced airlines to cancel flights in the Middle East, close airspace, and raised new security concerns for commercial aviation. Delta Air Lines has postponed its direct Atlanta-Riyadh route, originally scheduled to launch this Sunday, until March next year. Aviation security experts note that civil aviation is becoming a direct target of geopolitical conflicts, a "new paradigm" not seen in decades.
