Iran Air retires last Airbus A300B4 ending global passenger service for type

The prolonged use of the A300B4 by Iran Air is attributed largely to sanctions that limit access to new aircraft. These restrictions prevent Iranian carriers from purchasing planes with US-made components, effectively blocking deliveries from Boeing and most Airbus models. As a result, airlines like Iran Air rely on older jets and sometimes obtain spare parts through unofficial channels or repurpose airframes acquired via indirect means.

"Earlier this year, Simple Flying reported that as of early 2025, around 132 A300s were still operational, almost all of them freighters. Passenger variants were only active with Iran Air, which continued flying the model long after other airlines retired it due to sanctions limiting its ability to acquire replacements."

Before joining Iran Air’s fleet in 2006, EP-IBG served with multiple operators including KarAir (later part of Finnair), Air Scandic, Caledonian Airways, MNG Airlines, and Turkish Airlines.

Sanctions remain a major factor shaping Iran’s aviation sector. In July this year five Boeing 777-200ERs were transferred to Iran under unclear circumstances; they are believed destined for another Iranian carrier despite ongoing restrictions.

Unless international measures change or are lifted, Iranian airlines are expected to continue operating aging fleets while occasionally acquiring additional used jets through complex registration or delivery routes.
