Perth (OZ) airport upgrade
 

We have all read about the woes at Perth airport. Looking more from the pax perspective, which airport design should we follow or any ideas on how the layout should be???

I would think that there should be a floor level for arrivals (ground) and upper floor for departures...... and fully separated. Multi level car parks behind terminal to suit.

I for one prefer Singapore, and I believe Hong Kong is very good, but haven't been there.

Any other ideas??
