Passengers
Passengers waiting in the passenger lounges

Security check points
The lines of passengers at the security check points
The lines of passengers going through the gates

The passengers walking through the concourses,
Passed the duty free shops
And the cocktail lounges
The windows in the cocktail lounges
Overlooking the planes on the runways

Air traffic controllers
Air traffic control towers

Flight patterns
Holding patterns
Take off clearance
Landing instructions

Arrivals
Departures
Destinations

The distant destinations of the passengers,
The transcontinental flights
The international flights
Non stop
And connecting flights

Pilots, stewardesses,
The stewardesses pushing the snack carts down the aisles
The pilots announcing approaching turbulence

Delays and cancellations,
Baggage claim carousels,
Electronic message boards
With their electronic messages

Arriving flights
Departing flights

Boarding sequences
And disembarking gangways
In flight movies
Emergency landing instructions

Runways and landing strips,
Flight paths and trajectories
