You Want it How, Exactly?

Break it down for me please.  I am still so confused by this video and song.  First they are in white and they are transparent in an airport and the people are moving so, so fast behind them and then they are in black outside of the plane and then, BAM back in the airport.  They go back and forth, back and forth but they NEVER EVEN GET ON THE PLANE.  Where were they going?  Are they afraid of flying?  Which one wants what, what way?  Help me!
