Any company providing fuel or landing services to Iranian carriers risks losing access to the US dollar system. Treasury Secretary Scott Bessent announced the measure to shut down all Iranian airlines worldwide on September 23, following a September 8 move to pull licenses for foreign aircraft operations. The order includes a 15 day wind down window for those currently doing business with Tehran.

Two Iraqi government sources told AFP that Baghdad will ban US-sanctioned Iranian carriers starting Tuesday at dawn. The restrictions target a network primarily focused on Dubai, Istanbul, and Doha, coming as President Trump told Fox News that his options for Iran include "letting them rot economically" or "wiping Iran out."
