Turkish Airlines and Peers Suspend Iran Flights Amid Escalating US Sanctions

Key Facts

1Turkish Airlines, Pegasus, and AJet have cancelled flights to and from Iran starting September 21 as US sanctions take effect.

2Turkey revoked the banking license of Iran's Bank Mellat, which had operated in the country for decades.

3New US sanctions prevent Airbus aircraft containing American-made components from flying to Iran.

In a move reflecting heightened geopolitical pressure on Middle Eastern aviation, major Turkish carriers have suspended operations to Iran. According to reports, Turkish Airlines, Pegasus, and AJet cancelled all flights to and from Iran effective September 21, 2026, as new US sanctions take hold. These measures specifically target aircraft containing American-made components, including Airbus models, effectively preventing Turkish carriers from maintaining their Iranian routes under the new regulatory framework implemented by the US Treasury.

Alongside the aviation blockade, Turkish regulators have intensified financial restrictions by revoking the banking license of Iran's Bank Mellat, which had operated in Turkey for several decades. This coordination with US policy, led by Treasury Secretary Scott Bessent, marks a significant shift in regional dynamics. Per market data, these sanctions are designed to sever Iranian airlines from global services, including fuel access and airport support, significantly increasing the economic isolation of the Iranian aviation sector.

Global markets are currently monitoring the impact of these sanctions on regional stability and energy flows, noting that US API Crude Oil Stocks rose by 7.14 million barrels as of September 15, 2026. While specific instrument prices were unavailable at the close of September 22, 2026, the outlook for regional transport remains bearish. Investors should look toward upcoming trade balance data and US initial jobless claims for broader signals on how geopolitical friction is influencing global commercial activity.
