Sun Country Airlines

Sun Country Airlines maintains a commendable safety record, with no fatalities in its operational history since its founding. While generally considered safe, there have been a few notable incidents, such as an engine failure on a Boeing 737-800 in July 2025 (which resulted in an emergency landing without fatalities), and a pilot deviation incident in 2017 that led to a near collision.

The airline is recognized by the International Air Transport Association (IATA) and has successfully completed the IATA Operational Safety Audit (IOSA) multiple times, demonstrating its adherence to leading safety best practices. Sun Country is also certified by the Federal Aviation Administration (FAA) and operates as a Part 121 carrier, which requires strict compliance with aviation standards. Sun Country Airlines is not listed on the European Union's Air Safety List, which bans or restricts airlines that do not meet international safety standards.

Sun Country's fleet primarily consists of Boeing 737-800 aircraft. As of late 2024 to mid-2025, the average age of its passenger Boeing 737-800s is approximately 16.1 to 16.6 years, while its Boeing 737-800 Boeing Converted Freighters (BCF) have an average age of 22.1 years. The airline's CEO has stated plans to operate its Boeing 737-800s for at least another 15 years, emphasizing continued investment in their reliability. However, in 2025, Sun Country announced a temporary reduction in its operational fleet due to industry-wide shortages of spare parts and rising maintenance costs.
