Finnair has a legendary safety record in the modern jet era, but it did experience fatal accidents in its early history when operating as Aero O/Y. The deadliest was Aero Flight 311 in 1961, where a Douglas DC-3 crashed in Kvevlax, Finland, killing all 25 people on board. The investigation notoriously found that both pilots were intoxicated. Another major accident occurred in 1963 (Flight 217), which also involved a DC-3 and resulted in 22 fatalities. Since transitioning to the "Finnair" brand and modern jet aircraft, the airline has not had a single fatal passenger accident. In 2026, Finnair is consistently ranked among the safest airlines in the world by JACDEC and AirlineRatings, having maintained a clean sheet for over 60 years. This makes it a top choice for travelers prioritizing security and operational excellence on long-haul routes between Europe and Asia.
