A feathery passenger was discovered 12 hours into a 14-hour flight between Singapore and London.

The stowaway, a mynah bird, appeared in the business class section of a Singapore Airlines flight last Monday.

An airline spokesman confirmed the incident a week later, and said the bird was eventually caught.

In a Facebook video, it can be seen making itself comfortable on top of a headrest before a flight attendant makes a failed attempted to grab it.
