In partnership with Porto Alegre City Hall, the "Flash Mob Natal em Dança" took place at Porto Alegre Airport on the morning of December 3. The event is part of the program for Natal Alegre 2019, a City Hall project that celebrates the date with various activities throughout the month.

Passengers, visitors and the airport community followed the performance, which began with the song "Noite Feliz". Surprised, the audience moved towards the melody. The artistic intervention took place on Level 1, in the airport lobby, and featured 24 dancers from the New School Dreams (Porto Alegre) and GOA (Novo Hamburgo) groups.
