Probe underway as 7 flight attendants sickened by baffling odor on major airline

An incoming flight to Hawaii prompted an emergency response after multiple crew members began feeling ill during the journey.

The incident unfolded Sept. 24 aboard Alaska Airlines Flight 803, operated as Hawaiian Airlines between Los Angeles and Honolulu, Alaska Airlines told Fox News Digital.

Upon arrival, seven flight attendants were evaluated and released by medical personnel. No passengers required medical attention, Alaska Airlines said.

"Safety is our priority, and we thank the medical professionals for their response," the airline said in a statement to Fox News Digital.

First responders from multiple city and state agencies had been waiting at the airport ahead of the flight's arrival around 12:30 p.m., according to local news outlet Hawaii News Now.

The source of the odor has not been publicly identified.

Following the incident, the aircraft was being inspected before returning to service, according to Hawaii News Now.

Fox News Digital previously reported on another flight disrupted after an unusual odor was detected onboard.

American Airlines said the smell was traced to an onboard oven. Paramedics met the aircraft after it landed in Dublin, where several flight attendants and one passenger were reportedly evaluated and released.
