DHL, the delivery company has an interesting ad campaign in the Central MTR station (MTR is the subway). First there’s a huge board – the same as in an old airport – showing the daily arrival / departure schedule of flights. On the concourse near the platform they have a huge, life-size set of airplane landing gear and a design like a runway, illustrating their many flights throughout the Asia. During peak commuting time in the station they even had a man dressed up as a runway worker standing around!
