Iran’s Civil Aviation Organisation said on Tuesday, September 22, 2026, that international flights by Iranian airlines are operating as scheduled and that no foreign service has been cancelled, according to the ISNA agency, cited by Middle East Eye.

The body said no instruction has been issued to halt foreign flights and that passengers would be informed in advance of any schedule change. The statement answers the US Treasury Department’s announcement, which on Monday, September 21, sanctioned 36 targets tied to Iran’s aviation sector and suspended three authorisations that allowed overflights and the entry into Iran of foreign-operated aircraft of US origin or control, according to the Treasury’s release. Treasury Secretary Scott Bessent told CNBC that “on September 23, all Iranian airlines will be grounded globally”, and that the threat also covers airports, fuel suppliers and ticketing agencies, according to the The Jerusalem Post.
