Alaska Airlines Flight 892 returned to Honolulu International Airport Wednesday night due to an odor in the cabin, state transportation spokesman Tim Sakahara said.

“The plane landed safely. No passengers were injured,” Sakahara said.

Emergency Medical Services transported the crew members to a hospital in stable condition after they experienced nausea and headaches while aboard the plane, possibly from fumes.

Sakahara said four flight crew members were transported to the hospital for evaluation at their request.

Sakahara said no airport operations were affected.

According to an Alaska Airlines schedule, Flight 892 departs at 4:10 p.m. Wednesday from Honolulu and normally takes about 5-1/2 hours to arrive in San Diego.
