A woman captured the unusual footage - which has since gone viral - of the worker who climbed into the small space on a recent Southwest Airlines flight from Nashville to Philadelphia.

Taking to Twitter, the user captioned the image: ''Is this a dream @SouthwestAir ? (sic)''

She added: ''I can't get over how weird I find this. @SouthwestAir please get it together (sic)''

However, coming to the employee's defence, Southwest simply said the flight attendant was ''demonstrating a sense of humour''.

A representative for Southwest said in a statement to Fox News: ''Southwest Employees are known for demonstrating their sense of humour and unique personalities.

''In this instance, one of our Flight Attendants attempted to have a brief moment of fun with Customers during boarding. Of course, this is not our normal procedure, and Southwest Crews always maintain Safety as their top priority.''
