This is a very big airport
And all the staff that's working here seem young.
They were friendly and courteous.
Flew with air China here
Immigration was a breeze and they have these automatic machines which scan your passport and take your fingerprints. To my surprise the machine switched to hindi as soon as I scanned my Indian passport that was kinda cool but its hindi was a bit off.
Only thing I had trouble was communicating with the staff some of whom dont seem to speak English and might have a communication gap there.
Restrooms were clean.
Overall a nice airport.
But could be better.
