HONOLULU — A Southwest Airlines flight bound for Las Vegas was forced to reverse course over the Pacific Ocean and make an emergency diversion on Sunday, July 5, 2026, after a mid-flight issue prompted pilots to issue a distress call.
Southwest Airlines Flight WN139, operated by a Boeing 737 MAX 8 (registration N8773Q), departed Kahului Airport (OGG) on Maui on Sunday evening, tracking normally toward its mainland destination of Harry Reid International Airport (LAS).
However, approximately 90 minutes into the multi-hour journey, while the twin-engine jet was cruising at an altitude of 32,000 feet, the flight crew aborted the mainland crossing and initiated a sharp U-turn over the open ocean.
Chronology of the Diversion
- Departure: Flight WN139 departs Kahului (OGG) bound for Las Vegas.
- 90 Minutes In: While cruising at 32,000 feet, the aircraft turns around.
- Distress Call: The flight crew squawks 7700, the standard international transponder code signaling an inflight emergency.
- Diversion: Rather than attempting to return to Maui, the pilots opt for Daniel K. Inouye International Airport (HNL) in Honolulu due to its expansive emergency response capabilities and longer runways.
- Arrival: The aircraft lands safely in Honolulu after spending more than three hours airborne.
Precaution Over the Pacific
While the specific mechanical or operational nature of the emergency has not yet been confirmed by Southwest Airlines, turning around 90 minutes into an overwater flight is standard procedure under ETOPS (Extended-range Twin-engine Operational Performance Standards) regulations if an aircraft encounters a system anomaly. When flying between Hawaii and the US mainland, flights reach a “point of safe return”—once an issue arises prior to that point, returning to the islands is the primary protocol.
Emergency services were on standby at Honolulu International Airport as a standard precautionary measure. No injuries have been reported among the passengers or crew.
UPDATE
Landed on runway at 09:47 UTC.
