There seems to be an exhibition booth set up in the arrival hall concourse in KLIA for a few months already. It has the shape of a tunnel or some sort.
On closer inspection I found out the exhibition is in conjunction with the recent achievement by KLIA which was once voted again as the world's best airport for 15-25 million passengers per annum category.
It pretty much goes through the history and later the upgrading work of almost all the airports in Malaysia.
The history and development of the previous nation's international airport, the Sultan Abdul Aziz Airport in Subang seems to be quite comprehensive.
Let's hope our airports nationwide will strive for continuous improvement.
