• Iran's Civil Aviation Organization says US sanctions won't stop flight operations.
• Sanctions may increase costs but won't halt aviation industry.
• Iranian airlines have continued to operate despite years of restrictions.
• US Treasury Department imposed new sanctions on 27 Iranian airlines.

The US sanctions may indicate a continued effort to pressure Iran's economy, but they could also suggest a limited impact on the country's aviation industry, which may adapt and find ways to operate despite restrictions. This development may signal a broader trend of resilience in Iran's aviation sector, which could have implications for regional air travel and trade.
