Supposed new things should be better and much improved for the future 10-20 years. Unfortunately this long awaited new Phuket international terminal doesn't show it. The terminal is about 3 times bigger than the old one (which is still in use for domestic flights). The airline counters are more spacious and the air-conditioning is a lot better than SUV. That's it.
The most important part is the processing time of the passengers clearing thru' the customs and immigration. It takes almost an hour to get it thru' - twice slower than the old terminal. Once again, I really don't know why the computer system can be that backward or worse than the 80's. The airport lounges are even worse. The lounge is the same size as the old one but serving more than 20 airlines. I couldn't stand it but found the public area much more spacious and relaxing than the lounge. I heard some passengers furiously complain to the staff of the lounge by claiming "the worst lounge ever had...etc.".
