A plane belonging to Caspian Airlines, based in Iran, was seized at İstanbul Airport on Monday due to an outstanding debt of approximately €3 million (roughly $3.4 million). The Boeing 737 was prevented from departing for Tehran after passengers had completed boarding. Both Turkish and Iranian media outlets reported the incident, indicating a financial dispute led to the enforcement action. Passengers were reportedly ordered off the plane shortly before the scheduled departure. The seizure highlights potential financial pressures faced by Iranian airlines and legal proceedings within Türkiye. Details surrounding the exact nature of the debt remain unclear, but the incident underscores the complexities of international air travel and financial obligations. The plane remains impounded at İstanbul Airport as of this report.
