Seven flight attendants got sick from an unexplained smell on a Hawaiian Airlines flight from Los Angeles to Honolulu — bad for the crew, though the illness appears mild.

• An unknown odor was reported in the cabin as the plane landed at Daniel K. Inouye International Airport.
• Emergency crews treated seven flight attendants for nausea and headaches at the gate.
• All seven turned down a trip to the hospital.
• None of the 252 passengers on board reported problems.

Outlook: The source of the smell has not been identified, and the aircraft will likely be checked before returning to service.
