Finnair is one of the oldest airlines in the world and one of the safest. They have had no fatal or hull-loss accidents since 1963.

Finnair is widely regarded as one of the safest airlines in the world, and in the "modern era" of jet aviation, it has maintained a virtually spotless safety record. The airline has not had a fatal accident involving a passenger jet since it began jet operations in the 1960s. However, in its earlier history as Aero O/Y, there were three significant fatal incidents. The most recent occurred on November 8, 1963, when a Douglas DC-3 crashed on approach to Mariehamn due to a faulty altimeter and poor visibility, resulting in 22 fatalities. Before that, in 1961, another DC-3 crashed in Koivulahti due to pilot error, and in 1940, a Junkers Ju 52 was shot down by Soviet bombers during the Winter War. In 2026, Finnair consistently ranks in the top 10 of the JACDEC and AirlineRatings safety indexes. For over 60 years, they have operated one of the most reliable networks in the industry, particularly on their long-haul routes between Europe and Asia, making them a gold standard for safety-conscious travelers.
