Several countries have suspended flights to and from Iran after the US threatened to "shut down" Iranian carriers, part of President Trump's economic-pressure campaign. Oman and Azerbaijan have barred Iranian airlines from operating to their territories. Iraq, citing US sanctions on firms providing services to Iran's aviation sector, has banned flights to Baghdad. Georgia has suspended commercial services to Tbilisi. Mahan Air, one of Iran's largest carriers, has halted services to Istanbul, Ankara and Muscat.
