Recently, 300 Cathay Airlines flight attendants, agents, and even pilots performed to holiday songs in an amazingly synchronized flash dance at the Hong Kong international airport. The surprise performance began with a beautiful flight attendant suddenly stopping in the middle of the airport lobby, and the rest you just have to see.

Here's part 1 of the flash dance video:

The performance wasn't just meant to surprise the passengers. More importantly, it was a fundraiser to help Operation Santa Claus, an annual charity campaign which has funded projects in the areas of Children and Youth, Elderly, Medical, Physical and Mental Disabilities, Environment, and Social Enterprises for the last 26 years.

Thank you, Cathay Airlines agents, flight attendants, pilots and everyone else who is helping to spread the holiday spirit and cheer.
