Airline stocks experienced broad declines on Tuesday. United Airlines (UAL.US) and American Airlines (AAL.US) both fell by more than 5%, while Delta Air Lines (DAL.US) dropped over 4%. The downturn follows escalating conflicts involving the US, Israel, and Iran, which have caused significant disruptions to global flight operations. Analysts warn that the impact of this disruption could persist for several weeks. It has been reported that Dubai International Airport, the world's busiest international aviation hub, along with Doha Airport, have been closed for a third consecutive day, leaving tens of thousands of passengers stranded. The airline industry is now confronting its most severe challenge since the COVID-19 pandemic.
