This may seem like a stupidly obvious question, but is 'at the airport terminal' based on an actual experience you've had travelling overseas in a plane or is it something else?
that particular song came to me after doing a series of domestic flights, with some change-overs. the first verse seems to reflect the feeling of an airport terminal during the course of a travel itinerary. and the rest of the song seems to represent the feelings of commercial airline travel in general
