The first impression of Bangkok for me is Thai food. :)
In this airport, what attracts me the most is its architectural transparent facade and design. Cable truss system supporting the glass facades of the terminal building. 
The rectangular pattern louvers provide shading to the laminated glass cable facade.
In Suvarnabhumi International Airport terminal,
double large panels laminated glass.
Skylight roof.
laminated glass can reduce the airport noise into the interior in acoustically.
Sun-shading trellis
No early check-in service provided in this airport.
Duty free shops locate nearby each gate, similar to shopping mall. Often walk through those shop around before reach the lounge or gate, the time is near for boarding.
