Malaysia Airlines is investigating an Australian television report that claimed the co-pilot on its missing flight had invited two women to stay in the cockpit for the duration of a flight two years ago.
Fariq Abdul Hamid is accused of breaking the airline's rules by allowing Jonti Roos and Jaan Maree to join them in the cabin for a flight from Phuket to Kuala Lumpur in December 2011, and allegedly posing for pictures with the women and smoking cigarettes.
"Throughout the entire flight they were talking to us, and they were actually smoking throughout the flight," Ms Roos said on the program "A Current Affair".
Malaysia Airlines told the Associated Press that it would not comment on the report until the investigation into the claims had concluded.
Hamid, who has flown for the airline since 2007, is among the 239 people missing after a flight to Beijing disappeared on Friday night.
