Turkish Airlines, Pegasus & AJet Cancel Iran Flights As US Sanctions Bite

“Near-term Turkish airline earnings are at risk from sanctions-linked aircraft access and financing limits, but the hit may prove temporary if waivers or non-US financing options emerge.”

Sanctions risk hitting Turkish carriers' Iran routes is credible, but the article leaves unanswered questions. First, how long will the supply restrictions last, and will carve-outs exist for maintenance and essential operations? Second, Iran’s aviation demand, plus Turkey’s own tourism and trade flows, could shift rather than vanish, leaving some exposure but not a collapse. Third, Turkey’s banks and currency may face pressure from sanction spillovers, potentially hurting credit conditions for borrowers in the sector. Finally, the headline may overstate permanent flight bans; airlines could reroute, re-lease aircraft, or switch to non-US parts where feasible.

“Turkey is systematically decoupling its financial and aviation infrastructure from Iran to mitigate the risk of secondary US sanctions on its own banking sector.”

This signals a structural pivot in Turkey’s regional economic alignment. By revoking Bank Mellat’s license and grounding flights, Ankara is prioritizing compliance with US Treasury sanctions to protect its own access to Western capital markets and Boeing-heavy supply chains. This is a significant risk for the Turkish aviation sector, specifically Turkish Airlines (THYAO.IS), as it loses a high-margin regional hub route. The systemic risk here isn't just the lost revenue; it’s the potential for Turkey to be caught in a 'secondary sanction' trap that could impair its broader banking sector. If Erdogan is forced to choose between Iranian energy ties and Western financial integration, the latter is clearly winning.

“This is political realignment disguised as compliance—Erdogan is actively decoupling from Iran, not passively obeying US pressure, which signals a durable shift in Turkish foreign policy with long-term implications for regional trade and geopolitics.”

The article presents this as a sanctions squeeze, but the real story is Erdogan's political realignment. Turkish carriers cancelling Iran flights isn't forced compliance—it's a deliberate policy choice. Turkey just revoked Bank Mellat's license and seized Golden Global Investment Bank; these aren't reactive moves to US sanctions, they're proactive ones. Erdogan is signaling a shift away from Iran toward Trump's orbit. The 'no guarantee' language from Turkish Airlines suggests this is indefinite, not temporary. For Turkish equities and regional trade flows, this signals a structural reorientation, not a cyclical disruption.

“Sanctions compliance costs and lost connectivity will pressure Turkish airline margins more than the article's narrow focus on flights suggests.”

Turkish carriers face direct revenue hits from Iran route cancellations, with THYAO and PGSUS losing access through March 2027 at minimum. US sanctions on Airbus components amplify compliance costs beyond Boeing fleets, risking further route cuts if Turkey tightens alignment with Washington. Iran traffic is small but the precedent matters: any spillover to energy imports or Bank Mellat-style banking curbs could raise Turkish borrowing costs. Second-order effect is potential NATO friction if Erdogan pushes back.
