An unintended passenger, a feathery one, was discovered 12 hours into a flight from Singapore to London.
The stowaway, a mynah bird, appeared in the business class section of a Singapore Airlines flight last Monday, reports the Straits Times.
A typical Singapore-London flight takes about 14 hours. An airline spokesman confirmed the incident a week later and said the bird was eventually caught.
In a Facebook video, the bird can be seen perched, seemingly unfazed, on top of an unsuspecting passenger's headrest.
An air steward is seen making a grab for the bird but it evades capture.
"It was subsequently caught by cabin crew with the assistance of some of the passengers," the Strait Times report quoted a Singapore Airlines spokesperson.
The bird, which is native to southern Asia, was then handed over to animal quarantine authorities at London's Heathrow airport, the airlines said.
It, however, did not say how the bird made it into the main cabin while at Singapore's Changi Airport, or where it was hiding for the first 12 hours of the flight.
