The thieves who wait for airline passengers to sleep

Reports from Hong Kong and Singapore show how cabin thieves exploit crowded overhead bins and sleeping passengers. The clearest route data points to flights arriving in Hong Kong, though it cannot establish which individual flight is most dangerous.

A passenger settles in for the night, leaving a wallet inside a bag in the overhead bin. By landing, the wallet is gone. The thief may have spent the flight walking the aisle and opening bags while their owners slept.

The scale of the problem is clearest in Hong Kong. Authorities recorded 169 thefts on flights arriving in the city in the first ten months of 2024. About 70 per cent occurred on short-haul services, principally from Malaysia, Thailand, India and Vietnam. Another 20 per cent were on flights from the Middle East, including Dubai, Turkey and Doha. Those figures identify where reported cases occurred; without passenger or flight totals for comparison, they do not establish a league table of the most dangerous routes.

The thefts are not confined to Hong Kong-bound aircraft. Singapore police have reported cases on flights from Dubai, Kuala Lumpur and Korea, as well as a Singapore–Jakarta service. In one Korea–Singapore case investigated in May 2026, police said a man took a passenger’s bag from an overhead compartment and carried it several rows away. On a Kuala Lumpur–Singapore flight in June 2025, nearby passengers noticed suspicious behaviour and kept watch. 

Aviation blogger Sam Chui has drawn attention to footage of a suspected theft on a Hong Kong–Incheon flight. In an accompanying post, he described thieves working “in an organized chain during overnight flight when passengers fall asleep.” He urged witnesses to speak up if they see something strange on board.

Chui has also suggested a more elaborate network in which accomplices identify valuable targets before boarding and pass stolen goods between passengers. Speaking to 8days, he said his account drew on social-media comments and information gathered from the aviation industry. Those claims are a lead for investigators, but the published police accounts cited here do not establish that such a network operated in each case. The documented method is simpler: a thief opens or moves another passenger’s bag and takes cash, cards or other valuables while attention is elsewhere.  

For travellers, the practical precaution is equally simple. Keep passports, money, cards and jewellery on your person or within reach, and tell cabin crew immediately if you see someone searching a bag that may not be theirs. Singapore police specifically advise passengers to watch for people retrieving luggage and rummaging through overhead compartments.
