US sanctions on Iran's aviation industry make travel less predictable as countries cancel flights

US sanctions are pushing Iran's weakened aviation sector toward deeper isolation , making international travel less predictable and raising new risks for trade and cargo. Earlier in September as part of "operation economic outcast," the US Treasury Department targeted Iran's aviation sector, including Iranian airlines and companies providing ground handling, ticketing or airport support, which face secondary sanctions and potentially lose access to the US financial system. The United States cannot directly order foreign airports to reject Iranian aircraft. But the threat of secondary sanctions can make servicing them too risky for airports, fuel suppliers and aviation companies.
