MUSCAT, OMAN — Oman Air is set to retire its five Boeing 737-900ER jetliners between late 2024 and late 2025 as part of its narrowbody fleet renewal strategy. 

Recently, Sun Country Airlines acquired the planes directly from lessor GOAL and will lease them to Oman Air until the original lease expiration dates, which range from November 2024 to November 2025. Afterward, the aircraft will join Sun Country's fleet.

Sun Country will invest in acquiring the aircraft now while receiving lease revenue through 2025. The airline noted that supply chain constraints and engineering support have impacted used aircraft induction lead times. This transaction allows Sun Country to minimize the time required for aircraft modification and integration into revenue service.

Delivered new to Oman Air in 2014-2015, the aircraft were under 10-year leases. In addition to these planes, Oman Air's narrowbody fleet includes fourteen Boeing 737-800s (with only eight currently active) and thirteen Boeing 737 MAX 8s. The airline also has five 737 MAX 8s on firm order directly from the American planemaker.
