South Korea's transport ministry says Korean Air Lines Co. will face sanctions for pressuring employees to lie during a government probe into the nut rage incident.

The transport ministry said Tuesday Korean Air could face up to 21 days of flight suspensions or a $1.3 million fine for violating aviation law.

Cho Hyun-ah, the daughter of Korean Air's chairman, ordered a crew member off a Dec. 5 flight, forcing it to return to the gate, after she was served macadamia nuts in a bag, instead of on a plate.

The ministry said the airline will also be punished because Cho lied during the probe and because the captain was negligent in his duties.

It said Cho used abusive language to flight attendants but could not ascertain if she used violence.
