I think this song is about someone he loves who he's now out of touch with. Things didn't work out and he can see her slipping away right before his eyes, and he's just not ready for it. And she doesn't notice that he wants her back, she ignores him. So "the airway" is the distance between them. And he wishes they were in love, instead of the distance, which refers to "in love in the airway".
