That has left tens of thousands of passengers stranded as aviation faced its biggest test since the COVID-19 pandemic. The war sent U.S. airline shares lower on Monday, with Delta Air Lines, United Airlines and American Airlines falling between 2% and 4%. Shares in TUI, Europe's largest travel company, closed down 9.9% while Germany's Lufthansa declined by 5.2% and British Airways owner IAG lost 5.5%. Singapore Airlines cancelled flights to and from Dubai through March 7 while Japan Airlines suspended Tokyo-Doha services. Lufthansa cancelled passenger flights in and out of the United Arab Emirates, while Qatar Airways passengers in Sydney told Reuters they scrambled to rearrange travel with little information.
