A delight for sadomasochists. Not quite the worst in the world, though. Many Immigration officers treat you with huge contempt. Most are simply carrying out a function without any interest, but there are those who seek only to make life difficult, with a sneer. Object, and be threatened with incarceration. Beware the airport officials attempting to extort money! The facilities are improving, but not nearly fast enough. Outside, there is a waiting area for those desperate for work, where the privileged arrive in relative style, while guards in military uniform are waiting eagerly to administer a beating to the underprivileged. In about 100 years, they'll be ready to join the 20th century.

The most beautiful airport that I have ever seen.

Coming back to Immigration officials, one passenger comment's "The immigration officials are slow and cumbersome; they needs basic training in keyboarding and data entry...they all use one finger for type." This problem can be solved:
1. Replace the current officers with young officers, who know computer typing with at least 30 wpm and have MS office knowledge.
2. Schedule mandatory computer training for Immigration and Custom officers.
3. Recruit some lady officers to give live in these areas.

Compared to what it has been few years ago, ZIA is now at a good shape and appears to be under good maintenance. An army of more efficient airport staffs can make it a real world-class airport.

This is an International Airport, it has developed in recent times (spacious car-parking was built. However there are many improvement areas yet to be addressed:-
1. There is no flight display board outside in the public waiting area.
2. People would often disturb foreigners by asking for tips, the police are not at all active in preventing that.
3. Taxis operating within the airport are often accused of ripping off passengers in the middle of the road.
