Finnair cabin crew perform Bollywood routine

Passengers aboard a Finnair flight were treated to a surprise Bollywood dance routine from cabin crew staff this week.

To celebrate India's 63rd Republic Day, around 24 staff members on the Helsinki to New Delhi flight performed a choreographed routine, which has received over 1.5 million views on YouTube so far.

Flight attendant Helena Kaartinen came up with the idea and contacted her Bollywood teacher friend to help create the dance.

"It was a good way to show respect [to Indian culture]," she told the New York Times.

The crew danced to 'Deewangi Deewangi' from the film Om Shanti Om, directed and choreographed by Farah Khan.

Kaartinen is said to have worked for Finnair for 32 years and recruited staff members for the stunt in December, followed by twice weekly rehearsals near Helsinki Airport.
