Pretty sure the airport is LAX based on the tower in the background... based on the angles and building layout, I would take a guess and say that it's probably a window in terminal two that faces towards terminal three.

Might be terminal one though (where SWA operates out of) looking at terminal two... It kinda looks like that might be a Virgin Atlantic 747 in the background, but the aircraft in the foreground doesn't look like SWA, America West or USAirways, which is what operates out of those gates...
