It's BIAXIDENT from a band called Liquid Tension Experiment. Then, the song from the hotel part is called LIQUID DREAMS.
From the moment I first heard Biaxident, I knew I'd use it for something like this.
Quoting BEYBOS (Reply 5): i was acually surprised to see that they let you film when boreding the aircraft and inside the airport
Well I kinda did my trick. Not much of a trick though. I have a Canon handycam which is not big and perfectly fits in my hand. So I put the camera between my right pant pocket and my hand, pretending I just had my arms down... Then, inside the airport, no one ever called...
