The Iran war is causing major disruption to the travel industry, with over 52,000 flights cancelled since the war began on Feb. 28. Fuel prices have also increased, with some airlines already raising prices. The industry warns that a sustained conflict could have significant impacts on prices across the industry. Meanwhile, airport security lines have become too long due to the partial government shutdown. This could be a significant shift in American travel habits, similar to the 1970s when high gas prices led to significant changes in fuel consumption.
