War in Iran sparks global travel chaos

Tens of thousands of travelers - and pieces of cargo - are stranded around the globe today. That's because several countries in the Middle East closed their airspace after the US and Israel launched strikes on Iran over the weekend. It was followed by retaliatory airstrikes by Tehran on Israel and several Gulf Arab countries with US bases, causing the widespread cancellations and delays at some of the world's busiest airports. As The World's Transportation Correspondent Jeremy Siegel reports, the conflict has sparked one of the most significant disruptions to air travel in recent history.
