Context:

Iran's airspace was temporarily closed to most flights amid rising tensions with the U.S., following President Trump's threats of intervention related to recent anti-government protests in Iran. The closure, which lasted from late Wednesday to early Thursday, exempted approved international flights to and from Tehran and resulted in various airlines rerouting flights. Trump's comments indicated a potential de-escalation, as he noted a halt in the killings of protestors. The U.S. has withdrawn some military personnel from the Middle East amidst threats from Iran, prompting further flight cancellations and rerouting by several airlines. The situation remains fluid, with implications for regional air travel and security.
