Canada’s Nolinor Aviation is notable for having the oldest active commercial passenger jet in the world, or at least the oldest regular passenger fleet in a Western country. There may be small passenger airlines in Africa or Russia with older regional aircraft, e.g., the Angara Airlines Flight 2311 An-24 that crashed in 2025 was 49 years old. That said, Nolinor has the oldest Western-built airliner in regular passenger service. Even in sanctioned Iran, the oldest fleets are typically between 30 and 35 years old on average.
