Cathay Pacific cabin crew have been caught stealing ice cream, champagne and even pieces of bread from flights.
The airline has launched a major crackdown after repeated thefts have cost it "untold hundreds of millions" over the years.
Items such as mini tubs of Haagen-Dazs ice cream, bottles of champagne and cutlery are said to have gone missing.
Cathay Pacific crew now face the consequences if they help themselves to in-flight supplies.
The cabin crew under investigation have varying levels of experience.
All airlines have a policy where staff are not allowed to take company property, said Venus Fung, Chairperson of the Cabin Attendants Union of Hong Kong, but she called for more empathy from Cathay for its staff, saying that the spot checks showed little respect for the crew. "We are dealing with cases in a fair and reasonable manner in accordance with standard internal procedure".
Ed Higgs, general manager of in-flight services for the airline, said employees would be inspected by a security team on leaving an aircraft "for any items that you may have in your possession when you have been or are on company property".
'If anyone removes company property, irrespective of the value or if you believe it will be thrown away, you will be subject to discipline which may include termination'.
Cathay Pacific has been in dispute with employees before over petty theft.
Cheng-lin, who was striking for better crew working conditions, was later exonerated after a five-year legal battle for defamation.
Cathay Pacific recently became one of the first airlines in Asia to scrap its skirts-only policy for female flight attendants.
Apparently, flight attendants have been stealing so much stuff from the over-supplied planes that it ended up putting a serious dent in its profits.
